The same force is applied separately to two objects, A and B. B has twice the mass of A. What happens?
Alexeev081 [22]

Answer:

B's acceleration is half that of A

Explanation:

The force equation is;

Force = mass × acceleration

According to Newton's second law of motion, which explains the relationship between acceleration and mass of an object, an inverse relationship exists between the mass and the acceleration. For the same amount of force, an increase in mass (m) means a constant decrease in acceleration (a) of the object. In other words, if the mass of an object increases by two times, the acceleration will decrease by two times.

In this case involving objects A and B which has the same amount of force applied, object B has TWICE the mass of A. Using Newton's second law, this means that object B's ACCELERATION WILL BE HALF OF THAT OF OBJECT A.

What is the wavelength of a microwave with a frequency of 2450 mhz
JulsSmile [24]

Answer:

See below

Explanation:

The way to calculate this

  speed of light =  wavelength * frequency

   3 x 10 ^8 m/s   =   wavelength * 2450000000 Hz

       wavelength = .12245 meters

                    = 1.2245 x 10^-1  Meters
