An automobile of mass 1.46 E3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. The
centripetal force exerted on the automobile while rounding the curve is:
Answer:
Centripetal force = 13140 Newton.
Explanation:
Given the following data;
Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg
Velocity = 15m/s
Radius, r = 25m
To find the centripetal force, we would use the following formula:
Centripetal force = mv²/r
Substituting into the equation, we have;
Centripetal force = (1460*15²)/25
Centripetal force = (1460 * 225)/25
Centripetal force = 328500/25
Centripetal force = 13140 Newton.

Bode made a rocket using an empty plastic bottle and fins made out of cardboard. After partially filling the bottle with water, he
pumps air into the bottle using a pump attached to the rocket with plastic tubes. When the pressure in the bottle becomes high
enough the water gushes out and launches the rocket into the air, as shown in the diagram below.

How does the force that causes the water to leave the rocket compare to the force that causes the rocket to launch?
They are ental
Answer:They are equal and act in opposite directions.
Explanation:Newton's third law of motion states that for every action there is an equal and opposite reaction. In the case of Bode's rocket, the pressurized air in the bottle forces the water to gush downward out of the bottle, causing the rocket to launch upward into the air. The force of the water gushing downward is equal to the upward force on the rocket. So, the two forces are equal and act in opposite directions.
The force that causes the water to leave the rocket compared to the force that causes the force to launch is equal but opposite in direction.
What is Newton's law?There is a threes law given by the scientist newton in relation to the motion. The first law tells that if a body is in stop mode, then they become in motion once an external force is applied to them. The second law tells that force is equal to the product of mass and acceleration of the body. The third law tells that if you apply force to an object, then the object also applies force in reaction.
According to Newton's third law, the rocket applies force to the water, then the water also exerts a force on the rocket.
In the instance of Bode's rocket, the bottle's pressured air causes the water to pour out of the bottle downward, which causes the rocket to shoot upward into the air. The upward force on the rocket is equivalent to the force of the water pouring down. Therefore, the two forces are equivalent and exert opposing forces.

29. A wave source approaches your location, describe
the shift in wavelength and frequency you will
perceive.
Answer:
The waves travel at the same speed, but the observed frequency depends on any relative motion between the observer and source. When the observed frequency changes, so does the wavelength. If the observer and source are moving toward each other, then the frequency increases and the wavelength decreases.
3 Describe the two possible things that can happen if a charged object is brought near
another charged object,
4 Give one example of a balloon repelling another object, Explain why the balloon repelled
the object
Answer:
For two objects of charges q1 and q2, that are separated by a distance R, the force that each object suffers is given by the Coulomb's:
F = k*q1*q2/R^2
If both charges have the same sign, then we have a positive force, which means that the objects are "pushing" each other, then this is a repulsive force.
If instead, each object has a charge with a different sign, the force will be negative, then the objects will be pulling each other, and the force is an attractive force.
a) Whit this in mind, the two possible things that can happen if a charged object is near another charged object are:
The objects repel each other, which happens when both objects have charges with the same sign.
The objects attract each other, which happens when the objects have charges with a different sign.
b) A charged balloon most probably has a static charge (the type of charge that can be obtained by rubbing the balloon with a piece of cloth), which means that it has extra electrons, and we know that electrons have a negative charge, then we can assume that this balloon has a negative charge.
Then if we put another charged balloon (also with static charge) near our original balloon they will repel each other, this happens because both balloons have a negative charge.

Sometimes an electric bulb does not glow even if it is connected to the cell. What could be the reason
Answer:
Probable Reason - Break in filament of electric bulb
Explanation:
An electric bulb might not glow even if it is connected to the cell, possibly because of break in the filament of electric bulb. As, break in bulb's filament implies break in flow of electric current - between electric cells' terminal.
An evident example of this is , a fuse bulb doesn't light up as the current doesn't pass through filament.

Question: A pinball machine's plunger has a spring constant of 22
N/m and is compressed by 0.04 m to start a 0.006 kg pinball.
1. What is the elastic potential energy before the ball is released?
2. What is the kinetic energy of the pinball the instant it leaves the
spring?
3. What is the speed of the pinball the instant it leaves the spring?
4. If the pinball is moving at 1.3 m/s as it is deflected horizontally
across the top of the pinball machine, how much higher above the
ground is this part of its path when compared to its starting
position?

Answer:
1. The elastic potential energy is 0.0176 Joules
2. The kinetic energy of the pinball the instant it leaves the spring is 0.0176 Joules
3. The speed of the pinball the instant it leaves the spring is approximately 2.42212 m/s
4. The height of the part where the pinball is located on the machine above the ground is approximately 0.213 meters
Explanation:
The spring constant of the pinball machine's plunger, k = 22 N/m
The amount by which the pinball machine's plunger is compressed, x = 0.04 m
The mass of the pinball ball, m = 0.006 kg
1. The elastic potential energy, P.E. = 1/2·k·x²
By substitution, we get;
P.E. = 1/2 × 22 N/m × (0.04 m)² = 0.0176 J
The elastic potential energy, P.E. = 0.0176 J
2. At the instant the pinball leaves the spring, the plunger and therefore the force of the plunger no longer acts on the pinball
Since there are no external forces acting on the pinball to increase the speed of the pinball after it leaves the spring, the velocity reached is its maximum velocity, and therefore, the kinetic energy, K.E. is the maximum kinetic energy which by the conservation of energy, is equal to the initial potential energy
Therefore;
K.E. = P.E. = 0.0176 J
The kinetic energy of the pinball the instant it leaves the spring, K.E.= 0.0176 J
3. The kinetic energy, K.E., is given by the following formula;
K.E. = 1/2·m·v²
Where;
v = The speed or velocity of the object having kinetic energy K.E.
Therefore, from K.E. = 0.0176 J, and by plugging in the values of the variables, we have;
K.E. = 0.0176 J = 1/2 × 0.006 kg × v²
v² = 0.0176 J/(1/2 × 0.006 kg) = 88/15 m²/s²
v = √(88/15 m²/s²) ≈ (2·√330)/15 m/s ≈ 2.42212 m/s
The speed of the pinball the instant it leaves the spring, v ≈ 2.42212 m/s
4. The height of the pinball is given by the following kinematic equation of motion;
[tex]v_h[/tex]² = u² - 2·g·h
Where;
[tex]v_h[/tex] = The velocity of the pinball at the given height = 1.3 m/s
u = v ≈ 2.42212 m/s (The initial velocity of the pinball as it the spring)
g = The acceleration due to gravity ≈ 9.8 m/s²
h = The height of the pinball above the ground
We get;
[tex]v_h[/tex]² = 1.3² = 2.42212² - 2 × 9.8 × h
∴ h = (2.42212² - 1.3²)/(2 × 9.8) ≈ 0.213
The height of the part where the pinball is located on the machine above the ground, h ≈ 0.213 m

Take the upward and to-the-right directions to be positive (so down and to-the-left are negative).
The vertical forces acting on the object cancel, 6 N - 6 N = 0.
The horizontal forces exert a net force of 20 N - 3 N = 17 N. This net force is positive, so it points to the right. So the answer is A.

what physical properties dose plutonium
Answer:
Explanation:
Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in most reactor fuel; hence plutonium-239 is continuously made in these reactors. Since plutonium-239 can itself be split by neutrons to release energy, plutonium-239 provides a portion of the energy generation in a nuclear reactor.

So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.
Please answer this question.
Answer:
150.15 J
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 5 kg
Height (h) = 3 m
Kinetic energy (KE) =?
Next, we shall determine the velocity of the toy before hitting the ground. This can be obtained as follow:
Initial velocity (u) = 0 m/s
Height (h) = 3 m
Acceleration due to gravity (g) = 9.8 m/s²
Final velocity (v) =?
v² = u² + 2gh
v² = 0² + (2 × 10 × 3)
v² = 0 + 60
v² = 60
Take the square root of both side
v = √60
v = 7.75 m/s
Thus, the velocity of the toy before hitting the ground is 7.75 m/s.
Finally, we shall determine the kinetic energy of the toy before hitting the ground. This can be obtained as follow:
Mass (m) = 5 kg
Velocity (v) = 7.75 m/s.
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 5 × 7.75²
KE = 2.5 × 60.06
KE = 150.15 J
Thus, the kinetic energy of the toy before hitting the ground is 150.15 J
So this is physics any suggestions?
