Answer:
Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up.
Explanation:
Hope this helps! Good Luck on the rest of your assignments! :)
Answer:
Distance is quite literally the total amount of distance you have covered. Displacement is the total displacement from your origin. For example, if you were to move 5m north then 2m south, your total displacement from your origin would be 3m north.
The flow of air caused by blend in the blank creates distant blank on earth surface
Question:
The flow of air caused by _____ and the Coriolis effect creates distinct _____ on Earth's surface.
Answer:
Differences in heatingWind patternsExplanation:
The flow of air caused by variations in the rate at which the different parts are heated up as well as the Coriolis effect combine to create distinct wind patterns on Earth's surface.
The Coriolis Effect is used to describe a "force" that causes things (like objects, planes, air currents) traveling long distances around the Earth to appear to bend as they move rather than in a straight line.

Green light (520 nm) enters glass with n = 1.52. What is speed of light in the glass?
Answer:
1.97 * 10^8 m/s
Explanation:
Given that:
n = 1.52
Recall : speed of light (c) = 3 * 10^8 m/s
Speed (v) of light in glass:
v = speed of light / n
v = (3 * 10^8) / 1.52
v = 1.9736 * 10^8
Hence, speed of light in glass :
v = 1.97 * 10^8 m/s

Explanation:
An astronaut with mass ma is within a satellite that orbits earth at a height h above its surface. The correct expression for the gravitational force exerted on the astronaut by Earth on the basis described can be,
Fg=G MeMa/r²e
What is gravitational force?
Gravity is a basic interaction in physics that produces mutual attraction between all entities that have mass or energy.
Gravity maintains the planets around the sun and the moon orbiting the Earth. The moon's gravitational pull attracts water, causing ocean tides. Gravity creates stars and planets by attracting the elements that go into their formation.
Gravity waves are 'ripples' in space-time caused by some of the most destructive and powerful occurrences in the Universe. In the year 1916, Albert Einstein used to predicted the existence of gravitational waves which can be popularly known as general theory of relativity.
The gravitational force has the lowest non-contact strength in nature. It adheres to the inverse square law. It is always positive. It is directly proportional to the product of the two bodies' masses.
Thus, the equation can be written as,
Fg=G MeMa/r²e

water is not used as thermometric liquid.why?
Answer:
Water cannot be used in thermometer because of its higher freezing point and lower boiling point than other liquids . If water is used in a thermometer , it will start phase change at 0[tex]degree\\[/tex]C and 100[tex]degree[/tex]C and will not measure temperature , out of this range . This range is very small as compared to other liquids as mercury , having freezing point about −39[tex]degree[/tex]C and boiling point 356[tex]degree[/tex]C.
Explanation:
An object at rest has no net force acting on it.

A student releases a marble from the top of a ramp and the marble increases speed steadily and travels 190 cm in 4.10 s what's the marbles final speed
Answer:
The value is [tex]v = 92.68 \ cm/s[/tex]
Explanation:
From the question we are told that
The distance traveled is [tex]d = 190 \ cm = 1.9 \ m[/tex]
The time taken is [tex]t = 4.10 \ s[/tex]
Generally from kinematic equation we have that
[tex]s = ut + \frac{1}{2} at^2[/tex]
Here u is the initial velocity of the marble and the value is [tex]u = 0 \ m/s[/tex]
So
[tex]1.90 = 0* t + \frac{1}{2} a (4.10 )^2[/tex]
=> [tex]1.90 = 0* t + \frac{1}{2} a (4.10 )^2[/tex]
=> [tex]a = 0.226 \ m/s^2[/tex]
Generally from kinematic equations we have that
[tex]v = u + at[/tex]
=> [tex]v = 0 +0.226 * 4.10[/tex]
=> [tex]v =0.9268 \ m/s[/tex]
Converting to cm/s
=> [tex]v =0.9268 * 100[/tex]
=> [tex]v = 92.68 \ cm/s[/tex]

A softball pitcher rotates a 0.250 kg ball around a vertical circular path of radius 0.5 m before releasing it. The pitcher exerts a 33.0 N force directed parallel to the motion of the ball around the complete circular path. The speed of the ball at the top of the circle is 13.0 m/s. If the ball is released at the bottom of the circle, what is its speed upon release
Answer:
The value is [tex]u = 27.93 \ m/s[/tex]
Explanation:
From the question we are told that
The mass of the ball is [tex]m = 0.250 \ kg[/tex]
The radius of the circle is [tex]r = 0.5 \ m[/tex]
The force exerted is [tex]F = 33 \ N[/tex]
The speed of the ball on top of the circle is [tex]v = 13.0 \ m/s[/tex]
Gnerally from the law of energy conservation we have that
[tex]PE + W = \Delta KE[/tex]
Here PE is the potential energy of the pitcher which is mathematically represented as
[tex]PE = m * g * (2 r )[/tex]
=> [tex]PE = 0.250 * 9.8 * (2 * 0.5 )[/tex]
=> [tex]PE = 24.5\ J[/tex]
And W is the workdone by the force applied which is mathematically represented as
[tex]W = F * \pi * r[/tex]
=> [tex]W = 33 * 3.142 * 0.5[/tex]
=> [tex]W = 51.84 \ J[/tex]
And [tex]\Delta KE[/tex] is the change in kinetic energy which is mathematically represented as
[tex]\Delta KE = \frac{1}{2} * m * (v^2 - u^2 )[/tex]
=> [tex]\Delta KE = \frac{1}{2} * 0.250 * ( 13^2 - u^2 )[/tex]
=> [tex]\Delta KE = 0.125 * ( 13^2 - u^2 )[/tex]
=> [tex]\Delta KE = 21.125 - 0.125u^2[/tex]
So
[tex]24.5 + 51.84 = 21.125 - 0.125u^2[/tex]
=> [tex]u = 27.93 \ m/s[/tex]
The velocity of the ball released at the bottom is required.
The velocity of the ball released at the bottom is 24.56 m/s
F = Force = 33 N
r = Radius of loop = 0.5 m
m = Mass of ball = 0.25 kg
u = Initial velocity of ball = 13 m/s
v = Final velocity
g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
The energy balance of the system is given by
[tex]F\pi r+mg2r=\dfrac{1}{2}m(v^2-u^2)\\\Rightarrow v=\sqrt{\dfrac{2}{m}(F\pi r+mg2r)+u^2}\\\Rightarrow v=\sqrt{\dfrac{2}{0.25}(33\times \pi\times 0.5+0.25\times 9.81\times 2\times 0.5)+13^2}\\\Rightarrow v=24.56\ \text{m/s}[/tex]
The velocity of the ball released at the bottom is 24.56 m/s.

In which of these reactions is energy released?
A. Exothermic reactions
B. No reactions
C. All reactions
D. Endothermic reactions
Answer:
exothermic reaction
Explanation:
Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.

Answer:
199,430Joules
Explanation:
Gravitational potential energy is the energy possessed by a falling object due to virtue of its position.
gravitational potential energy = mass * acceleration due to gravity * height
gravitational potential energy = 55 * 9.8 * 370
gravitational potential energy = 539 * 370
gravitational potential energy = 199,430
Hence the total change in the skier's gravitational potential energy is 199,430Joules
