Answer:
F=ma
Explanation:
The Newton's laws of motion tries to explain the how bodies behave and the energy changes when theys are in motion. For the 3 of them to hold, the bodies must be moving in a straight line and with constant velocity.
The second one states that, "the change of momentum of a moving body is directly proportional to the force producing it and it takes place to the direction of force."
From the choices given, the appropriate answer is F=ma
When two objects collide is the answer...Hope this helps :)
Remember, Your electric field lines drawn from positive charge (protons) and goes to negative charge (electron)
So, Your Answers would be:
15) B) Positive
16) A) Negative
17) B) Positive
18) A) Negative
19) B) Positive
20) B) Positive
Hope this helps!
Answer:
a = 50 [m/s²]
Explanation:
This type of problem can be solved using Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.
∑F = m*a
where:
F = force =25 [N] (units of Newtons)
m = mass = 0.5 [kg]
a = acceleration [m/s²]
![a=F/m\\a=25/0.5\\a= 50 [m/s^{2}]](https://tex.z-dn.net/?f=a%3DF%2Fm%5C%5Ca%3D25%2F0.5%5C%5Ca%3D%2050%20%5Bm%2Fs%5E%7B2%7D%5D)
Answer: absorbed by the object
Explanation: When a light wave with a single frequency strikes an object, a number of things could happen. The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object
