Answer:
= 30N - 10N = 20N
Please mark as brainliest!
It is appreciated hope this helps!
Explanation:
I have put what a simple free body force diagram that you would need for this question below!
Just swap out the 5N and 3N with 30N and 10N :)
To solve this problem we will apply the relation of Ohm's law, at the same time we will use the concept of resistance in a cable, resistivity and potential difference.
According to Ohm's law we have to
Here,
V = Voltage
I = Current
R = Resistance
At the same time resistance can be described as
Here,
= Resistivity of the material
l = Length of the specimen
A = Cross-sectional area
From the above expression we can write the current as,
Replacing we have that,
Therefore the current in the wire is 3.809A
<em>Note: The value obtained for the resistivity of Tungsten was theoretically obtained and can be consulted online.</em>
Answer:
d)energy
Explanation:
Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.
<h3><u>Given</u><u>:</u><u>-</u></h3>

Calculate the mass.
<h3><u>Solution:-</u><u> </u></h3>
As We know that,
★ Putting the values in the above formula,we get:
well in my own words, i'd saw the the doppler effect is similar to light because sound has a speed, and light does too.
so my theory is if you go fast enough everything would just become black, or maybe white? idk its hard to explain
but what my point is, is taht the doppler effect works in the same way, like if a car is moving towards you the sound is being emitted from the car and being pushed by the speed of the car making it have a much higher pitch, when the car is going away however it drops to a lower pitch due the the sound waves being DRAGGED by the car.
there hoped this helped I guess
