Answer:
12
Explanation:
The equation is w= f *d
36=3*d
12=d 12 units is the mass
Answer:
467kg
Explanation:
resultant force=2000-600=1400N
F=mass*acceleration
1400=m*3
m=467kg
Hope this can help you.
According to Newton's second law of motion, the force of the object applied to accelerate is equal to the mass of the object multiplied by the acceleration. However in reality, air friction are still considered. In this case, if the density of air is 0, hence vacuum and air is negligible, then mass and radius is proportional to the acceleration.
Answer:
The force of the radiation on the surface is 3.33 x 10⁻¹⁰ N
Explanation:
Given;
intensity of light, I = 1kw/m² = 1000 W/m²
area of the surface, A = 1 cm² = 1 x 10⁻⁴ m²
Since the light is completely absorbed, the force of the radiation is given by;
F = P/c
where;
c is the speed of light = 3 x 10⁸ m/s
But P = IA
F = IA /c
F = (1000 X 1 X 10⁻⁴) / 3 x 10⁸
F = 3.33 x 10⁻¹⁰ N
Therefore, the force of the radiation on the surface is 3.33 x 10⁻¹⁰ N
Answer:
