Answer:

Wavelength is the distance between from one crest to another crest or from one trough to another trough. The amplitude is the distance from the midpoint to the crest or trough. Crest is the highest point of the or a wave. Tough is the lowest point of the or a wave. Rest position is the position where it lies on the midpoint line.

A lamp that uses 100.0 watts of power requires a voltage of 210.0 volts. What is the resistance of the lamp?

alexandr402 [8]

Resistance = Voltage/Current
Wattage = Voltage * Current

<span> <span> </span> </span> That means the current drawn by the lamp is equal to 100 watts divided by 210 volts.

Resistance = $\frac{210}{ \frac{100}{210} }$

A sports car of mass 1000 kg can accelerate from rest to 27 m/s in 7.0 s. what is the average forward force on the car?

Marysya12 [62]

The average force on the car=3857 N

Explanation:

mass of car= 1000 kg

initial velocity= Vi=0

Final velocity= Vf=27 m/s

time= t= 7 s

using the kinematic equation,

Vf= Vi + at

27=0+a (7)

a=3.857 m/s²

Now the force is given by F= m a

F=1000 (3.857)

F=3857 N
