Answer:
10 m/s^2
Explanation:
Equation: F = ma.
a = acceleration
m = mass
F = force
Because we are trying to find acceleration instead of force we want to rearrange the equation to solve for a which is F/m = a.
F = 20
m = 2
a = ?
a = F/m
a = 20/2
a = 10 m/s^2
Answer:
F=1.14N j
Explanation:
The magnitude of the magnetic force over a charge in a constant magnetic field is given by the formula:
(|)
In this case v and B vectors are perpendicular between them. Furthermore the direction of the magnetic force is:
-i X k = +j
Finally, by replacing in (1) we obtain:

The frequency of a sound wave is the number of cycles of a sound wave per second or Hertz (Hz). The frequency can be calculated by dividing wavelength by time (Figure 1.3). A small wavelength will yield a higher frequency, whereas a larger wavelength will yield a smaller frequency.
Answer:
Explanation:
When the craft was stationary , weight will be balanced by tension
T = mg
T = 7000 N
A)
when the craft was being lowered to the seafloor
drag force will act in upper direction , so
T₁ + 1800 = mg
T₁ = mg - 1800
= 7000 - 1800
= 5200 N
52 X 10² N
B)
when the craft was being raised from the seafloor , Tension will act in downward direction
T₂ = mg+ 1800
T₂ = 7000 - 1800
= 8800N
