Since we know that
Gravitational potential energy = mass × height ×gravity
then
GPE = 1.5 kg x 0.500 m x 9.8m/s^2
therefore
GPE = 7.35 J
Answer:
About 8.3 minutes
Explanation:
Use the formula for velocity as the distance covered by the light divided the time it takes:
[/tex]
Use the information about the speed of light in vacuum: 
and the information you are given regarding the distance between Sun and Earth: 
to solve the first velocity equation for the unknown time "t":

we can convert second into minutes by dividing by 60: 500 s = 500/60 minutes = 8.3333... minutes
Answer:
The length of the closed tube is<u> </u>

Formula used :

Speed = v = 346 m/s


wavelength = 0.81 m
Answer:
The motion of a projectile consists of two independent motions:
- A uniform motion (constant velocity) along the horizontal direction
- A uniformly accelerated motion (constant acceleration, equal to the acceleration due to gravity) along the vertical direction
In terms of vectors, we have the following:
Velocity:
- The horizontal velocity does not change - therefore, this vector is constant
- The vertical velocity changes, as the vertical motion is accelerated - therefore, this vector changes. This is because there is a downward force acting on the projectile, the force of gravity.
Acceleration:
- There is no acceleration along the horizontal direction, so here the vector is zero
- The acceleration along the vertical direction is constant, and it is
in the downward direction (acceleration due to gravity)
