Answer:
Energy,
Explanation:
It is given that,
Mass of matter, m = 1 g = 0.001 Kg
If this matter is completely converted into energy, we need to find the yield. The mass of an object can be converted to energy as :
c = speed of light
So, the energy yield will be . Hence, this is the required solution.
What is the direction of the frictional force?
Answer:
Direction of friction is always opposite to relative motion
Explanation:
Friction always resist the relative motion of two surface so it is always opposite to the direction of relative velocity
What is the direction of the normal force?
Answer:
It is perpendicular to the contact plane
Explanation:
Normal force is the perpendicular force which is always at 90 degree with the contact surface
How does the frictional force depend on the normal force?
Answer:
Explanation:
Friction force is directly proportional to the normal force so we can say it is given as
Let the x-axis be parallel to the incline and the y-axis rise from the incline at a right angle. By Newton's second law, if there is no acceleration in the y-direction (perpendicular to the plane), what must be the magnitude of the normal force?
Answer:
Explanation:
Normal force is equal to the component of the weight opposite to the direction of normal force
Use Newton's second law and the x-components of the forces to find the acceleration. m/s2

As we know that
16. each side length will be 16
Answer:
Naturally occurring radio waves are made by lightning or by astronomical objects. Artificially generated radio waves are used for fixed and mobile radio communication, broadcasting, radar and other navigation systems, communications satellites, computer networks and innumerable other applications.
