Answer:
The answer will be 936 N.
Explanation:
Given that
m = 80 kg
Acceleration of the elevator , a= 1.7 m/s² ( upward)
The gravity force on the mass = m g
The reading on the scale = F N
Now by applying the Newton's second law
F - m g = ma
F= m g + m a
F= m ( g +a )
F= 80 ( 10 + 1.7 ) N ( take g= 10 m/s²)
F=80 x 11.7 N
F= 936 N
Therefore the reading on the scale will be 936 N.
The answer will be 936 N.
The weight could be different, metals have a higher mass than nonmetals, so when occupying the same amount of space, the weight of the metal is far more.
Answer:
the answer is true Induction charging is a method used to charge an object without actually touching the object to any other charged object.
Explanation:
Answer:
2.04 s
Explanation:
v = at + v₀
(-30.0 m/s) = (-9.8 m/s²) t + (-10.0 m/s)
t = 2.04 s
Answer:
at T = 0ºC the change of state is from the solid state to the gaseous state
Explanation:
In this exercise we are asked about the changes of state, from the data we will assume that the material is water.
Water can exist in three solid states, liquid and gas, in a graph of pressure ℗ against temperature (T) there is a point called triple at T = 0.01ºC, below this point the curve has two states at high pressure solid and low pressure gas.
As a result of the previous ones at T = 0ºC the change of state is from the solid state to the gaseous state
