If the slight resistance you feel from a light switch (when you flick it) is the reaction force, what is the action force?

3 0

Answer:

The action force is the force that causes a reaction, in this case, it will be flicking the switch, the resistance of the switch of being moved is what you "fell" as the resistance force. The correct option is A

Again, an action force is a given force in one direction, in this case, the spring is not stretching, but there is a force applied on it, so the action force will be the force of pulling the spring from both ends, in this case, the correct option is C

Answer:

Explanation:

If the passage of the waves is one crest every 2.5 seconds, then that is the frequency of the wave, f.

The distance between the 2 crests (or troughs) is the wavelength, λ.

We want the velocity of this wave. The equation that relates these 3 things is

f=\frac{v}{\lambda} and filling in:

2.5=\frac{v}{2.0} so

v = 2.5(2.0) and

v = 5.0 m/s

A toy race car travels down a 25cm ramp in 5 seconds. Calculate its speed. A. 125 cm/sec B. 5 cm/sec C. 0.2 cm/sec D. 20 cm/sec
kipiarov [429]
This would be B, 5cm/sec.
To get this answer you would need to divided 25 which is how large the ramp is, and 5 seconds, the amount of time it took to travel down the ramp.

An electrical appliance draws 9.0 amperes of current when connected to a 120-volt
Lemur [1.5K]

Answer:

The correct answer is "1080 W".

Explanation:

Given:

Current,

I = 9.0 A

Potential difference,

V = 120 volt

As we know,

⇒ Power=IV

On substituting the values, we get

⇒             =120\times 9.0

⇒             =1080 \ W
