what is the force if a block of wood with mass 20 kg slides along a frictionless surface at 2 m/s squared
CaHeK987 [17]

Answer:

40 N

Explanation:

F=ma where F is the applied force, m is the mass of object and a is the acceleration.

Since there is no friction, substituting 20 Kg for m and 2 m/s squared for a then we obtain

F=20*2=40 N

Prove for N/C=Volt/m
Zigmanuir [339]

Answer:

simple, Volt =change in potential energy/Charge

the unit of energy is newton meter (Force*distance)

the unit of charge is coloumb

So, Volt/meter=newton* meter/coloumb*meter

=newton/coloumb (hence proved)

This unit is the potential drop per unit of length in a conductive wire with uniform resistance

What is the frequency in hertz of a signal that repeats 80,000 times within one minute? What is its period?
Harman [31]

1333.3 is the frequency in the hertz of a signal that repeats 80,000 times within one minute. 0.00075 is its period.

The frequency of a repeated event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to underline differences with spatial and angular frequencies, respectively.

The length of time it takes for a particle in a medium to complete one full vibrational cycle is the period of a wave. Being a time, a period is measured in time units like seconds, hours, days, or years. The Earth's orbit around the Sun has a duration of around 365 days, and one cycle of the Earth lasts 365 days.

frequency = cycle /second

frequency = 80000 / 60

frequency = 1333.3 hertz

Period = 1 / frequency

Period = 1 / 1,333.3

Period = 0.00075

Electromagnetic waves differ from other types of waves because they are (2 points)
saveliy_v [14]

Answer:

b. able to travel through a vacuum.

Explanation:

The most distinguishing factor of an electromagnetic waves is that they are able to travel through a vacuum.

These waves do not require materials in a medium for propagation.

  • Electromagnetic waves are formed by the propagation of the electric and magnetic fields.
  • They vibrate at an angle of 90° .
  • They are unlike like mechanical waves that requires that requires materials in medium for their propagation.

A sprinter completes a 400m race (one lap around the track). Mr Borst thinks the magnitudes of her distance and displacement are
GalinKa [24]

Answer:

No

Explanation:

Displacement is how far between your initial and finishing position.

If one lap around the track is 400 m and the sprinter ran 1 lap around the track. Then the sprinter's distance is 400 m and their displacement is 0 m

If the sprinter ran 400 m in a straight line however, then it would be equal.

But since the sprinter ran 1 lap around there is no displacement.

I hope this helped you...
