The only two forces acting on a body have magnitudes of 20 n and 35 n and directions that differ by 80°. the resulting acceleration has a magnitude of 20 m/s^2. what is the mass of the body? o 2.4kg o 2.2kg o 2.7kg o 3.1kg

b) 2.2 kg

Explanation:

Net force acting on an object is the sum of the  two forces acting on the body.

The net force is calculated using the parallelogram law of vectors.

F =

Here A = 20 N , B = 35 N and θ =80°

Net Force = F = 43.22 N

Acceleration = a = 20 m/s/s

Since F = ma, m = F/a = 43.22 / 20 = 2.161 kg = 2.2 kg

heat the gas and measure the pressure

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
