Answer:
Explanation:
As the current carrying wire carries current in south to north direction, the direction of magnetic field is given by the Right hand thumb rule which is in anticlockwise direction so the magnetic compass deflects towards west.
C.
<span>Each atom has 19 proton
</span> the atomic number is the same as protons
For this problem, we will need the famous equation F=ma, as detailed by Isaac Newton.
F=mass x acceleration, where Force is in Newtons.
20 m/s represents the quantity of speed change, but to use in the equation, we need acceleration, not speed. Acceleration is the velocity change over a unit time, so changing 20 m/s in 0.1 seconds means that the acceleration was 200 m/s^2.
Plugging in all your numbers, you find:
F=(0.45 kg)(200 m/s^2) = 90 N of force.
Feeling of Weight.
When walking, you feel the weight on your feet, therefore, your brain automatically refers to it as a source of weight.
In the air there is no platform to land on, therefore the brain does not have the conscience to register you getting pulled down.
Answer:
The wavelength of the standing wave is 3 m.
Explanation:
Given that,
Length = 6 m
Nodes = 4
We need to calculate the wave length
Using formula of nodes


Where, l = length
n = number of nodes
= wavelength
Put the value into the formula


Hence, The wavelength of the standing wave is 3 m.
