<h3>
Answer:</h3>
30 m/s
<h3>
Explanation:</h3>
<u>We are given:</u>
Initial Velocity (u) = 0 m/s
Acceleration of the Car (a) = 3 m/s²
Time Interval (t) = 10 seconds
<u>Speed of the Car After 10 seconds:</u>
From the First equation of motion:
v = u + at
replacing the given values
v = 0 + (3)(10)
v = 30 m/s
Hence, the car is moving at a velocity of 30 m/s after 10 seconds
Answer:
3/4 filled with water
Explanation:
x = Fraction of box filled
g = Acceleration due to gravity = 9.81 m/s²
= Density of water
V = Volume of water
Weight of empty box is equal to the weight of the water displaced
As all the forces are conserved
So, the box starts to sink when the box is 3/4 filled with water
Imagine this, you hear an ambulance, The ambulance is about a mile off and it isn't very loud. As it gets closer it gets louder and louder when it passes you it gets loudest then it is very quiet. So yes, your hypothesis was correct.
