Using Fleming’s left hand rule,
The magnetic force on the electron will be west. Example: If it is dropped above the equator in Africa, the electron will head towards North America.
Answer:
7.0 m
Explanation:
Step 1: Given data
Initial speed of the ball (u): 1.8 m/s
Acceleration (a): 6.1 m/s²
Final speed of the ball (v): 9.4 m/s
Step 2: Calculate the displacement (s) of the ball
The ball is moving with a uniformly accelerated rectilinear motion. We can calculate the displacement using the following suvat equation.
v² = u² + 2 × a × s
s = (v² - u²)/2 × a
s = [(9.4 m/s)² - (1.8 m/s)²]/2 × 6.1 m/s²
s = 7.0 m

The magnetic field strenght on the z-axis at a distance d from the center is,
Our values are:
Replacing,
Liquids are ideally incompressible, so their volume barely changes. They also adapt to whichever shape.

Wave 3 will move the slowest, the statement could made about the data collected in Hamish's table
Answer: Option C
<u>Explanation:
</u>
Sound waves require medium to pass from one to another. Depending upon the density of molecules in the medium, the speed of the sound waves can be determined. As we know that compression and rarefactions will be formed for propagation of sound waves when the waves collide with molecules of the medium.
So, if there is less molecules present in the medium or loosely packed molecules present in the medium with high mean free path length than the sound wave will be travelling slowly in that medium.
Thus, as we known that gas has the loosely packed molecules among the other states of matter, so wave 3 which is made to pass through the gas medium will be propagation at the lowest speed or will move the slowest compared to other 3 gases made to propagate in solid and liquid mediums.
