Answer:
solar energy using solar panels
Explanation:
Answer:c
Explanation:because when u push the oar back u go forward
a) since a=0 therefore, friction force =0
b) friction = 59.5 × 1 =59.5 N.
c)maximum acceleration = 0.566 × g =5.54 m/s².
<h3>What is Friction force?</h3>
The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are various kinds of friction: Two solid surfaces in touch are opposed to one another's a relative lateral motion by dry friction.
<h3>What is acceleration?</h3>
Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities. The direction of the net force acting on an object determines the direction of its acceleration.
Hence, (a) since a=0 therefore, friction force =0, (b) friction = 59.5 × 1 =59.5 N, (c)maximum acceleration = 0.566 × g =5.54 m/s².

Answer:
Induced emf,
Explanation:
It is given that,
Rate of change of magnetic field,
A UHF antenna is oriented at an angle of 47° to a magnetic field, θ = 47°
Diameter of the antenna, d = 13.4 cm
Radius, r = 6.7 m = 0.067 m
We need to find the induced emf of the antenna. It is given by :
Where
= magnetic flux,
So,
B = magnetic field
So, the induced emf of the antenna is 2.2 mV. Hence, this is the required solution.
