Density = Mass per unit Volume
that is,
D = m / V
Now,
We've been provided with,
Density = 790 kg/m³
Volume = 1250 litres = 1.250 m³
Now,
987.5 kg of mass will a 1250 litres tank will hold.

Answer:
The net forces exerted on the horse and cart are not the same, so they are not balanced forces.
Explanation:
Using newton laws,
ΣF = ma
The two forces acting on the body is the forward force by the horse and the frictional force opposing the forward force
F-Fr= ma
Therefore,
F=ma+Fr
So the forward (by horse) is more than the opposite reaction (by cart).
The only time the forward force and the opposite reaction are the same is when a=0, I.e, the body is not moving at all or the body is moving at constant velocity.
Thomson's results from experiments with cathode ray tubes produced a big change in scientific thought about atoms because <u>his results gave the first evidence that atoms were made of smaller particles.</u>
Particularly, he proved the existence of negatively charged sub-atomic particles that are called as electrons which together with a positively charged nucleus form an atomic unit.
Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Thomson also made the following conclusions from his experiment:
- The cathode ray is composed of negatively-charged particles.
- The particles must be as part of an atom because the mass of each particle is only ~ 1/2000
compared to one hydrogen atom mass.
- Within the atoms of all elements, these subatomic particles are found.
Initially it was controversial, but later Thomson's discoveries were gradually accepted by scientists. After then, his cathode ray particles were given a name called as electrons.
Explanation:
In washing machine, the electrical energy is converted in kinetic energy then the mechanical energy is converted into thermal (heat) energy.
