Answer:
The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.
At point B, Alberto's distance covered increases with time, equal distance is covered in equal time interval. The speed increases uniformly. At the point C to D, the distance covered with time remains the same. At the point D, equal distance is no longer covered in equal time intervals.
According to the law of inertia, an object will remain at rest or in a state of uniform motion unless it is acted upon by an unbalanced force. This means that smokey mouse will continue moving uniformly unless a force acts on it.
From Newton's second law; F = ma and a = F/m. F = force , m= mass, a = acceleration. This implies that smokey mouse can increase its speed by;
Increasing the force acting on the mouse
Decreasing the mass of the mouse
Action and reaction is encountered as the mouse is walking. The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.
Explanation:
The frequency of the signal is
Explanation:
The relationship between wavelength, speed and frequency of an electromagnetic wave is
where
is the speed of light
f is the frequency of the wave
is the wavelength
For the radio wave in this problem,
is the wavelength
So we can rewrite the equation to find the frequency:

Answer:
V, W, and Y.
Explanation:
For a particle in uniform circular motion, the velocity vector remains constant in magnitude, but it continuously changes its direction. The velocity is tangent to the circle. The velocity vectors are all the same length.
