Answer:
Explanation:
if you bounce a tennis ball, it will come back up as an equal reaction to your action (dropping it). there is an equal but opposite reaction in this scenario, demonstrating newton's third law.
Formula: PE = mgh
m = 20 kg, g = 9.8 m/s^2 h= ?
1000 = 20 * 9.8 * h
1000 = 196h
h = 5.10204082
The height is around 5m
Answer:
The angular frequency is the coil rotating is 1.9 rad/s.
Explanation:
Given that,
Number of turns = 600
Radius = 15 cm
Magnetic field = 0.020 T
Maximum induced emf = 1.6 V
We need to calculate the angular frequency is the coil rotating
Using formula emf
When induced emf is maximum so 
will be 1.
Where, N = number of turns
A = area
B = magnetic field
Put the value into the formula
Hence, The angular frequency is the coil rotating is 1.9 rad/s.
Answer:
2) c) give-way vessel
3) a) With one short blast
Explanation:
2) A vessel that is required to take early substantial action to ensure avoiding collision called Give way vessel
In overtaking, the vessel intending to overtake is the Give-Way Vessel the vessel that is going to be overtaken is the Stand-On Vessel
Therefore, the correct option is c) give-way vessel
3) When vessels use sound signals in a meeting head on situation both vessel are Give-Way vessels and both vessel pass the each other by turning to the starboard side therefore they intend to pass each other on their port side requiring one short blast
Therefore, the correct option is a) With one short blast.
