A body moves in a perfectly circular path at constant speed. Are there forces acting on the system?.

Answers

Answer 1

A body moves in a perfectly circular path at constant speed. There must be a force pulling toward the center of the circle. According to Newton's first law, there must a force present to keep the object moving in a circle rather than a straight line.

About Newton's First law

Newton's 1st law is to show the resultant force acting on an object with a composition equal to zero, so that an object that is initially at rest will always remain at rest. While an object initially moves in a straight line, it will forever continue to move in a straight line at a constant speed. So it can be concluded that in Newton's Law 1 the acceleration of an object is directly proportional to the force acting on the object and inversely proportional to the mass or weight of the object itself.

The properties of objects in Newton's 1st law tend to maintain their original state with the same inertia or degree of inertia. That is why Newton's 1st Law is also known as the Law of Inertia. The shape of the moment of inertia in Newton's 1st Law occurs in various forms, for example linear moments of inertia, mass moments of inertia, and polar or polar moments of inertia.

The magnitude of the stresses also differ according to the material used, such as bending stress and torsional stress, so the calculation can be based on the moment of inertia

What is linear expansivity?​will receive brainliest if answered correctly​

Answers

Answer:

Linear expansivity is the fractional increase in length of a specimen of a solid, per unit rise in temperature. If a specimen increases in length from l1 to l2 when its temperature is raised θ°, then the expansivity (α) is given by: l2 = l1(1 + αθ). This relationship assumes that α is independent of temperature. This is not, in general, the case and a more accurate relationship is: l2 = l1(1 + aθ + bθ2 + cθ3…), where a, b, and c are constants.

l2 = l1(1 + αθ).

l2 = l1(1 + aθ + bθ2 + cθ3…),

Answer:

Linear expansivity is the fractional increase in length of a specimen of a solid, per unit rise in temperature. ... Superficial expansivity is the fractional increase in area of a solid surface caused by unit rise in temperature, i.e. A2 = A1(1 + βθ), where β is the superficial expansivity.

v = 150 m/s

Explanation:

Given that,

The acceleration of the ball, a = 10 m/s²

Time, t = 15 s

We need to find the increase in ball's velocity. When it is dropped its initial velocity is equal to 0. Let v be the velocity,

v = u+at

v = 0 +10(15)

v = 150 m/s

So, the ball's final velocity is 150 m/s.

P = 100/1

P = 100

Answer:

10 N / cm^2

Explanation:

The Formiula is P = F / A

P = presure

F = Force in Newtons

A = area.

The answer is the smaller the area the larger the pressure.

The smallest area you have given us is 10 cm^2

The Pressure = 100N / 10 cm^2

Pressure = 10 N/cm^2

if the charge of the force is doubled would the force double

Answers

Answer: The electrostatic force between two point charge particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. So, if you double the individual charges while keeping the same distance, the net electrostatic force will be four times the previous value.

Explanation:

Since, we know

F = (k×q1×q2)/r²

When the charges are doubled, we have :

F' = (k × 2q1 × 2q2)/r²

F' = 4 (k×q1×q2)/r²

Thus,

F' = 4F

Hence, the force becomes 4 times its initial value.

If there is zero total force acting on the refrigerator, the refrigerator would

A) slow down
B) speed up
C) remains the same speed
D) slow down, change direction and then speed up going the other way
E) remains at the same speed, but changes direction

Answers

Answer:

c

Explanation:

this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it

so if the resultant force on the refrigerator is 0N, but it was initially moving, it will continue in its motion in a straight line.

it will not change direction since it will continue in its uniform motion.

The car's overall displacement if, A car drives 40 km due east and then 50 km due west is 10 km in the west.

What is displacement?

Displacement is defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into account both the direction of the motion and the magnitude of the changing position. Displacement may be zero, positive, or negative.

Given:

A car drives 40 km due east and then 50 km due west,

Consider the west direction as positive and the east direction as negative, then,

The displacement = Displacement in the west + displacement in the east,

The displacement = 50 - 40

The displacement = 10

As the sign is positive, then the direction would be west.

Thus, the displacement of the car is +10 km.

Will the gravitational force between 2 objects increase or decrease if the distance between them decreases.

Answers

Answer:

increase

Explanation:

The formula for the gravitation for of attraction is:

[tex]F = \dfrac{Gm_1m_2}{r^2}[/tex]

It implies that the force of attraction is inversely proportional to the square of the distance. i.e.

[tex]F \infty \dfrac{1}{r^2}[/tex]

where;

G = gravitational constant

m = mass; &

r = distance between the two objects.

Now let's assume that the distance between is reduced from 1 to half;

Then:

[tex]F \infty \dfrac{1}{\Big (\dfrac{r}{2} \Big)^2}[/tex]

[tex]F \infty \dfrac{4}{r^2}[/tex]

Thus, the new gravitational force of attraction increased by a factor of 4.
