8 0

Answer:

25 m/s

Explanation:

First we should define the variables

T=4

Dx = 100

ay=-9.8

ax=0

We can use formula 1 from the BIG 5

x=(v+v0)t/2

By plugging in our variables we can get 100=4(v+v0)/2

Which is 50=v+v0

v=v0 since horizontal acceleration always equals zero

so 2v0 = 50

v0 = 25

Tritium and helium-3 have the same number of nucleons, but tritium has one proton and two neutrons whereas helium-3 has two prot
ryzh [129]

Answer:

Tritium is more stable.

This happens in part because the tritium nucleus has an extra neutron enhancing the nuclear forces.

Explanation:

The binding energy is the energy that holds nucleons together in the nucleus. It depends on the number of nucleons present in the nucleus. The greater the number of nucleons, the greater the binding energy.

Also, the more the number of neutrons in a nucleus, the greater the nuclear forces. Helium-3 has only one neutron while tritium has two neutrons. The extra neutron in tritium enhances the nuclear forces hence tritium has a greater binding energy than Helium-3

If a car travels 80 miles between 2 and 4 pm, then its velocity is close to 40 mph at 2 pm.
Alisiya [41]
The answer should be false because it doesnt say if the car is traveling at constant speed. The cars speed can be various so that in total for 2 hours that it travels it passes 80 miles. If however it actually traveled at constant speed than the answer is true.

Witch is true according to the law of conservation of energy?
Elanso [62]

Explanation:

The law of conservation of energy is one of the fundamental laws of science that helps to understand energy in nature.

Energy is the ability to do work. There are different forms of energy.

Generally, energy is classified into potential and kinetic forms of energy. Potential energy is the energy at rest in a body. It is due to the position of the body.

Kinetic energy is the energy due to the motion of a body.

There are different forms of kinetic and potential energy and they are related by the law of conservation of energy.

The law states that "in an isolated system, energy is neither created nor destroyed by transformed from one form to another".

An isolated system is a system in which there is no exchange of matter and energy.

Due to this we know that no new energy is created or destroyed, they are only transformed from one form to the other.
