Answer:4.5 joules
Explanation:
charge=3c
Potential difference=1.5v
Work=potential difference x charge
Work=1.5 x 3
Work=4.5
Work=4.5 joules
Answer:
D) side to side
Explanation:
The frictional force act on the cube in the side to side direction. The friction force acts opposite to the direction of the motion of an object which reduces its speed or sometimes prevent it from moving from one place to another. In order to reduce the force of friction, the body has to move by rolling instead of sliding and use of lubrication on the surface on which the object moves.
There is no lines that we can see. Also the rate of something has the biggest number or its either gonna be the longest line, yw .
Answer:
1039.23 m/s
Explanation:
Given:
Height, H = 3 x 10⁵m
acceleration of gravity on lo, a = 1.80 m/s² toward moon's surface i.e -1.80m/s² with respect to the earth
Now, at its highest point the velocity i.e the final velocity 'v' = 0m/s.
Now using the Newton's equation of motion
v² - u² =2as
where,
v = final velocity
u = initial velocity
a = acceleration
s = distance
now,
substituting the values we get
0²-u² = 2 × (-1.80) × 3 x 10⁵
or
Hence, the <u>initial velocity</u><u> with which the material is ejected is </u><u>1039.23 m/s</u>
