Answer:
150.5 m
Explanation:
The motion of the car is a uniformly accelerated motion, so we can use the following suvat equation to find the displacement:

where
s is the displacement
u is the initial velocity
t is the time
a is the acceleration
For the car in this problem,
u = 0

Substituting t = 8.9 s, we find the displacement of the car at that time:

Answer:
1) Work is a measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. 2) Work is calculated through joules. 3) It's possible to calculate work by multiplying the amount of force applied by the distance that the force is applied. If we know the amount of force the stick applies to the puck and the distance that the stick is applying the force to the puck, we can figure out the amount of work done.

Answer:
option A. Jovian
Explanation:
If we consider the temperature of the planet which is 50 K, shows that the planet is quite distant from the central point of the solar system which itself shows one of the characteristics of Jovian planets.
If escape velocities of the planets are to be considered than for terrestrial planets like that of our Earth, the escape velocity must be similar to that of the Earth which is 11.2 Km/s, quite a smaller value as the gravitational pull of Earth is stronger than that of the Jovian planets with much higher values of escape velocities as the mentioned one here is 30 km/s which is again indicative of the planet being a Jovian planet.
Hi there!
We can use the equation for the charge of a charging capacitor:

Using Capacitor equations:

Therefore, Cε equals the steady-state charge of the capacitor (the function approaches this value as t ⇒ ∞.
We can plug in the givens and solve.


Answer:
800J
Explanation:
Using the formula for change in the internal energy of a system
∆U = Q - W
Q = heat added to the system
W =workdone by system.
We know the process is an adiabatic one then, there no addition/ removal of heat, then Q= 0
(∆U = -W )
Then substitute for W, we have
∆U = -[-800]
∆U= 800J
∆U = 800J
