Answer:
The magnitude of the force the light beam exerts on the man is 5.9 x 10⁻⁵N
(b) the force the light beam exerts is much too small to be felt by the man.
Explanation:
Given;
cross-sectional area of the man, A = 0.500m²
intensity of light, I = 35.5kW/m²
If all the incident light were absorbed, the pressure of the incident light on the man can be calculated as follows;
P = I/c
where;
P is the pressure of the incident light
I is the intensity of the incident light
c is the speed of light
F = PA
where;
F is the force of the incident light on the man
P is the pressure of the incident light on the man
A is the cross-sectional area of the man
F = 1.18 x 10⁻⁴ x 0.5 = 5.9 x 10⁻⁵ N
The magnitude of the force the light beam exerts on the man is 5.9 x 10⁻⁵ N
Therefore, the force the light beam exerts is much too small to be felt by the man.
Answer:
The power of the distance is -1.
Explanation:
The equation for the electric potential of a point charge is given by
where V is the electric potential, k is Coulomb's constant (it has a value of with units
), q is the electric charge of the small charge and r is the distance from the charge.
Now, the power of a number is how many times we multiply that number by itself; we see r appears only once in the equation. So we know the power is 1. But we can see in the equation that k and q are divided by r, which means r is the denominator. This means the power of r is negative (-).
Therefore, the power of r is -1.
Answer:
Explanation:
From the question, acceleration from in 10 seconds.
Acceleration function can be written as:-
From the acceleration equation, we can obtain the velocity equation:
We calculate velocity after 10sec from the above v(t) as .
To obtain distance travelled after 10 seconds:-
Therefore 200m is for 10seconds, and next 200m at 30m/s
Total time=
