The answer is C 2800 kg m/s
Answer:
Two times
Explanation:
The crane lifts the cargo twice as high so the potential energy will increase twice the amount.
Answer:
A. Gasoline
B. Apple juice
Explanation:
A homogeneous mixture can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture.
For instance, aqueous hydrogen chloride, HCl(aq) is a homogeneous mixture. The aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride. This ultimately implies that, aqueous hydrogen chloride HCl(aq) is a solution of hydrogen chloride in water and it is commonly referred to as Hydrochloric acid.
Hence, the two mixtures that are homogeneous are gasoline and apple juice.
Answer:
The magnitude of the gravitational force which the astronaut experience in satellite 
Newton
Explanation:
As we know
Gravitational force F = 
Where G is the gravitational constant 
M is the mass of earth 
m is not given
r is the radius of earth 
Substituting the given values, we get -
Kg
Gravitational force in the satellite
N
