Answer:
4.2s
Explanation:
Given parameters:
Power = 2190W
Mass of box = 1.47 x 10⁴g
distance = 6.34 x 10⁴mm
Unknown:
Time = ?
Solution:
Power is the rate at which work is done;
Mathematically;
Power =
Time =
Work done = weight x height
convert mass to kg;
100g = 1kg;
1.47 x 10⁴g = 14.7kg
convert the height to m;
1000mm = 1m
6.34 x 10⁴mm gives 63.4m
Work done = 14.7 x 9.8 x 63.4 = 9133.4J
Time taken =
= 4.2s
Answer:
Net Force = 0
Explanation:
Causes objects to accelerate. Balanced Forces. Two equal forces push in opposite direction causing no change in motion causing net force = 0.

Explanation:
Malleable
Malleability
is a property of matter, that’s specializes in metals, in which these metals
can be bended, twisted or formed into a thinner sheets, and not being able to
shatter to pieces instead it can be formed into a new shape. Unlike the other
three, take for instance hardness. If a hard object such as wood for example
when used with an axe it breaks and it is lead to smithereens. Flammable like
is when applied to fire can dramatically explode when hit it obviously breaks.
