Explain the relationship between force, mass and acceleration in Newton's second law

Physics
1 answer:
Nikitich [7]3 years ago
7 0

Newton's  second law of motion describes what happens to a body when an external  force is applied to it.

Newton's second law of motion states that the force acting on an object is equal to the mass of that object times its acceleration. In mathematical form this is written as

F = ma

Where F is force , m is mass and a is acceleration. The math or logic  behind this is that if  you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half.

What is the energy of a single photon of visible light with a wavelength of 500.0 nm? 1 nm=10^−9 m
Dmitrij [34]

Answer:

3.97×10^−19 J

From the planks equation

E=hv

V= c/ wave length

V= 3×10^8/500×10^-9

=6×10^14

E= hv

6.63×10^-34×6×10^14

= 3.97×10^−19 J

Zeb was lifting a box onto a moving truck. He lifted with a net force of 2000N and the box had a mass of 100 kg. What was the re
Aleksandr [31]

Answer:

<h2>20 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{2000}{100}  = 20 \\

We have the final answer as

<h3>20 m/s²</h3>

Hope this helps you

How would life on earth be different if earth’s axis were not tilted with respect to its orbit?
Vladimir [108]

If Earth's axis was "straight up and down" instead of tilted, then ...

<span>-- There would be no seasons.

-- The climate at any one place would be the same all year around. 

-- The days would be the same length, everywhere,
    and all year around.

-- So would the nights.

-- The sun would be up a little more than 12 hours every day.
    It would be down a little less than 12 hours every day.

-- At the middle of the day, the sun would be at the same height
   in the sky all year around, not higher in some months and lower
   in others.

-- The equator would be the only place on Earth where the sun
    could ever be directly over your head.

-- If you were at the north pole or the south pole, the sun would be
   down on the horizon, and it would just go around and around you
   every day.  It would never rise or set, and it would never get any
   higher or lower.
