Answer: Option (C) is the correct answer.
Explanation:
An atom consists of three subatomic particles which are protons, neutrons and electrons.
The protons and neutrons are present inside the nucleus. Whereas electrons revolve around the nucleus.
Whenever there is a bond formed by loss, gain or sharing between any two atoms then it is due to the electrons.
Hence, we can conclude that atoms may be bonded together by losing, gaining, or sharing electrons.
b. convergent plate
c. divergent plate
d. transform boundary

Explanation:
This problem is an example of a perfectly inelastic collision. After the collision, the two cars merge into a single object. So in order to find the velocity of that object, we need to find the velocity of the center of mass of the given system of 2 cars.
Mass of Ford = = 2080 kg
Mass of truck = = 18400 kg
Velocity of Ford = = 22.6 m/s north
Velocity of truck = = 10.4 m/s east
Let us break up the velocity vector into 2 components, one along north () and one along east ().
Therefore,
(speed of truck along the north is zero)
Similarly,
(speed of Ford along the east is zero)
Hence, the resultant speed of the entangled cars is given by,
and the direction is given by (please refer to the figure attached),
The post-collision speed and direction of the two entangled vehicles, calculated using principles of momentum conservation and trigonometry, are found to be 9.82 m/s and 76.4 degrees east of north respectively.
In this scenario, we are dealing with the principles of momentum conservation. In a collision like this one, the total momentum before the collision equals the total momentum after the collision, as long as no external forces are acting on the system. The momentum (p) of an object is calculated as the mass (m) of the object multiplied by its velocity (v), or p=mv.
Before the collision, the total momentum of the system (ptotal) is the sum of the momentum of the Ford Explorer (pExplorer) and the garbage truck (ptruck). After the collision, they move together as a single object, so their combined mass and velocity would make up the total momentum.
Based on the given information, pExplorer = 2080 kg * 22.6 m/s = 47,008 kg*m/s and ptruck = 18400 kg * 10.4 m/s = 191,360 kg*m/s. The direction should also be taken into account. Since they are perpendicular to each other, we can use the Pythagorean Theorem to find the resultant momentum: (pExplorer)^2 + (ptruck)^2 = ptotal^2, which gives a total momentum of 201,262.8 kg*m/s.
Now, the total mass (mtotal) of two entangled vehicles is 2080 kg + 18400 kg = 20480 kg. Hence the velocity (v) of the two vehicles after the collision is calulated by ptotal divided by mtotal : 201262.8 kg*m/s / 20480 kg = 9.82 m/s. The direction is calculated using trigonometrics such as tan(-1)(ptruck / pExplorer) which gives a direction of 76.4 degrees east of north.

A. Nuclear fusion is used to power aircraft carriers.
B. Nuclear fusion is used in power plants to produce electricity.
C. Nuclear fusion requires very high pressures and temperatures.
D. Nuclear fusion occurs spontaneously on Earth.
C. Nuclear fusion requires very high pressures and temperatures.
Nuclear fusion involves the process of combining two light atomic nuclei to form a heavier nucleus, and it requires extremely high temperatures and pressures, as found in the core of stars. In contrast, nuclear fission is the process of splitting a heavy atomic nucleus into two or more lighter nuclei and typically occurs in nuclear power plants to produce electricity.
