Yes I can help jus tell me what the 26th question is
Power is the rate at which work is done (2nd option)
PE equals KE when KE is 50%.
Like below:
E = PE + KE
E = 50 + 50
E = 100.
Remember, both KE and PE always have to add up to 100 so that is why PE is equal to KE when KE is 50% of energy.
Hope I helped. :)
Answer:
B) 20N.s is the correct answer
Explanation:
The formula for the impulse is given as:
Impulse = change in momentum
Impulse = mass × change in speed
Impulse = m × ΔV
Given:
initial speed = 40m/s
Final speed = -60 m/s (Since the the ball will now move in the opposite direction after hitting the bat, the speed is negative)
mass = 0.20 kg
Thus, we have
Impulse = 0.20 × (40m/s - (-60)m/s)
Impulse = 0.20 × 100 = 20 kg-m/s or 20 N.s
For the answer to the question above, it is A. Sea Breeze or <span>on shore, </span>breeze<span> is a gentle wind blowing from the </span>sea<span> toward land, that develops over bodies of water near land due to differences in air pressure created by their different heat capacity. It is a common occurrence along coasts during the morning as solar radiation heats the land more quickly than the water.</span>
