Answer:
Two identical spheres are released from a device at time t = 0 from the same ... Sphere A has no initial velocity and falls straight down. ... (b) On the axes below, sketch and label a graph of the horizontal component of the velocity of sphere A and of sphere B as a function of time. ... Which ball has the greater vertical velocity
Explanation:
In order from shortest to longest frequency, the electromagnetic waves can be ranked :
1. X-rays
2. Ultraviolet
3. Infrared
4. Microwave
X-rays has the shortest frequency which ranges between 30 petahertz to 30 exahertz. X-rays have the smallest wavelengths at 0.01-10 nanometers. Its energy ranges between 100eV to 100keV.

Let your initial displacement from your home to the store be
Dd

1 and your displacement from the store to your friend’s house
be Dd

2.
Given: Dd

1 = 200 m [N]; Dd
>
2 = 600 m [S]
Required: Dd

T
Analysis: Dd

2
Solution: Figure 6 shows the given vectors, with the tip of Dd

1
joined to the tail of Dd

T is drawn in red,
from the tail of Dd

T is [S].
Dd

T measures 4 cm in length in Figure 6, so using the scale of
1 cm : 100 m, the actual magnitude of Dd

T is 400 m.
Statement: Relative to your starting point at your home, your
total displacement is 400 m [S].
Answer:
C. it will not change.
Explanation:
While combing, the rubbing of the comb with the hair, transfer of electron takes place from the hair to the comb and the comb becomes negatively charged. But, this transfer of electron does not make any considerable change in the mass of the hair. This is because the mass of an electron is highly negligible. Now, neglecting the mass of an electron, the transfer of the electrons from the hair to the comb makes charging of the comb, but no loss of mass in the hair. So, the mass of hair will no change.
