We Know, W = F * s
Here, F = 90 N
s = 35 m
Substitute it into expression,
W = 90 * 35
W = 3150 Joules
So, your final answer is 3150 Joules.
Hope this helps!
Answer:
The correct answer is - B ≠ 0, E = 0.
Explanation:
A force q E is exerted by the electric field on the charged particle that accelerates always, that is, it increases the speed of the particle. The particle can never be rotated in a rotation in the circle in an electric field.
The magnitude of the velocity cannot be changed by the magnetic field but changes only the velocity of the direction.
If the particle moves in a circle it means that the speed should begin for a year. The only direct velocity is constant and only the change be b can be achieved. So, B ≠ 0 and E = 0.
The correct answer is 223 days.
The relationship between the duration of revolution and the separation between the sun is shown by Kepler's third law. Using the notions of circular motion and the gravitational and centripetal forces, we may obtain this equation.
According to Kepler's third rule, the semi-major axis of an orbit is linked to the orbital period of a planet around the sun as follows:
p² = a³
where an is the semi-major axis/distance to the star and p is the orbital period in years.
It is said that a = 0.72 AU for Venus.
P= √(0.72 AU)^3 = 0.61 years.
365 days in a year = 222.9 ≈ 223 days.

Answer:
147.45 Hz
Explanation:
v = Speed of sound in water = 1482 m/s
= Speed of whale = 4.95 m/s
Frequency of the wave in stationary condition
Ship's frequency which is reflected back
The difference in frequency is given by
The difference in wavelength is 147.45 Hz
