Answer:
800J
Explanation:
Given data
Force= 100N
Distance moved= 8m
The expression for the work done is
WD= Force* distance
substitute
WD= 100*8
WD= 800Joules
Hence the work done is 800J
Answer:
The wavelength of the emitted photon is 413.6 nm
Explanation:
Given;
energy of the emitted photon, E = 3 eV = 3 x 1.602 x 10⁻¹⁹ J
speed of light, c = 3 x 10⁸ m/s
The energy of the emitted photon is given by;
E = hf
where;
h is Planck's constant = 6.626 x 10⁻³⁴ J/s
f is the frequency of the light = c / λ
λ is the wavelength
Therefore, the wavelength of the emitted photon is 413.6 nm
Answer:
The acceleration of the spacecraft is 16,367.62 miles/hr²
Explanation:
Given;
thrust of the spacecraft, F = 5.31 x 10⁶ N
mass of the spacecraft, m = 5,760,000 lbm = 2612692.051 kg
The acceleration of the spacecraft in m/s² is given by Newton's second law of motion;
F = ma
a = F / m
The acceleration in miles per hour square is given by;
Therefore, the acceleration of the spacecraft is 16,367.62 miles/hr²
According to the research, the correct answer is that higher latitudes are conditions that can cause hurricanes to change direction.
<h3>What are hurricanes?</h3>
It is a meteorological phenomenon that usually originates in the tropical areas of the lower atmosphere, being a wind of extraordinary force that forms a whirlwind.
In this sense, the direction of these winds is influenced by the rotation of the Earth (Coriolis effect) and that as they move a little towards the higher latitudes, the direction winds are reversed and blow from west to east.
Therefore, we can conclude that the condition that affects the direction of hurricanes is when these tropical phenomena reach the highest latitudes.

Answer:
(C) , The wires repel
Explanation:
We are given that
Length of wire=L=7 m
We have to find the magnitude and direction of the force that the two segments of this cord exert on each other.
Where
Using the formula
When the wires carrying current in equal current in opposite direction then, the wire repel to each other.
Hence, the wires repel to each other.
