Answer:
towards right so it is -15 degree
Explanation:
Net force in forward direction due to all three is given as
here we know that
Similarly in Y direction we will have
Now the net force on the donkey is given as
Now direction of force is given as
towards right so it is -15 degree
Ike is at the beach watching the waves in the ocean. Ike notices that some of the waves are short. Other waves are very tall and come up high above the water. Two waves that are different heights because They have different amplitudes.
Answer: Option (D) is correct
Explanation:
The different heights of the waves are due to their different amplitudes. The Amplitude of a particular wave depends upon the amount of energy being carried by waves. It the waves carry more energy than their amplitude will be higher.
But if energy carried by a wave is less than the wave will have a low amplitude. The Amplitude shows the distance covered from the rest position to peak position.
The law of conservation of energy states that in any reaction, energy cannot be created or destroyed.
In other words, energy has to be conserved in every reaction.
Answer:
Option C
Explanation:
From the question we are told that:
Mass 
Radius 
Time 
Generally the equation for Tension is mathematically given by
Therefore
, toward the center of the circle
Option C
The goal of scientific method is to produce public knowledge. That is knowledge available to any person with sufficient education, all such knowledge can be verified by or deduced from experiments and observations.
