Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that car is moving with uniform speed
so here net tangential force must be zero while in radial direction the car is moving in circle so here we have
so we have
R = 285 m
now we have
Part b)
As we know that Police Man is experiencing the force only towards the center of the circle
So the net force is horizontal towards the center of the circle and hence it angle with vertical will be
The force that will make this into
equilibrium would be equal to the force of equal amount yet applied on the
opposite direction.
<span>So we are given that a force of 55 N due west
was applied, so the equilibrium force would be 55 N due east.</span>
Answer:
White
Explanation:
White light is not a color, its'a combination of all colors, the same as black is the absence of all colors. Therefore it cannot be assigned a single wavelength. White light contains all wavelengths from about 390 nm to 700 nm.
It’s an assortment of compound molecules
Answer:
The particle speed is constant.
Explanation:
Particles in gases travel quickly in all directions, frequently clashing with each other and the container's edge. The particles gather kinetic energy and travel faster as the temperature rises. The true average speed of the particles is determined by their mass and temperature; larger particles travel more slower around the same temperature than lighter particles.
Thus, the false statement about a wave moving through a constant speed is that:
The particle speed is constant.
