Answer:
all objects in the universe.
Answer:
Explanation:
Step one:
Given data
work-done in dragging the trash= 236J
applied force= 18.9N
distance moved= 24.4m
Required
The angle of the applied force
Step two:
We know that work done is
WD= F * distance
<em>The work is the product of the horizontal component of the force and the distance.
</em>
Horizontal force = 236 ÷ 24.4
= 9.67 N
Cos θ = Horizontal force ÷ Actual force
Cos θ = (236 ÷ 24.4) ÷ 18.9 = 236 ÷ 461.16
The angle is approximately 59˚
Answer:
We cannot see anything in a completely dark room as there is no light present in the darkroom. (a) After switching on an electric bulb in the dark room as a light source, we can see it as it emits light that reaches our eyes directly.
Explanation:
Answer:
Difference: The weak force tears an atomic nucleus apart.The strong force is what keeps the protons and neutrons in a nucleus held together, while the weak force is what makes radioactive particles decay.Or even simpler: The strong force keeps stuff together while the weak force helps stuff split up.
Similarities: Weak force allows quarks to turn into other quarks, which can turn a neutron into a proton and break up the nucleus. ... One big difference is that the particles/fields that are responsible for carrying the strong force are massless, whereas for the weak force they are quite massive (nearly 100 times the proton mass).
your answer will be D Strong nuclear force is most like electric because they are both related to distance.
