Hydrogen bombs and stars both produce energy with nuclear _____.

Physics
1 answer:
Kruka [31]3 years ago
3 0

Answer;

- Nuclear fusion

Explanation;

-Hydrogen bombs and stars both produce energy with the nuclear fusion. On other side, the Sun and other stars make heat and light by nuclear reactions.

-The first stage of a hydrogen bomb involves a fission explosion which in turn leads to a nuclear fusion. The extreme heat and pressure from the initial atomic blast force together deuterium and tritium (two light gases made of hydrogen). When they are forced together, some of the hydrogen atoms fuse to one another, creating helium.

-This process of fusion releases even more energy per unit of mass than fission does, and the energy released from the fusion reaction also feeds back into the fission reaction, increasing its output.

When the weight of the object increase block what is the force of friction applied? Explanation?
erik [133]

Answer:

There is absolutely No relationship between the weight of an object (which is constant) and the frictional force. If a block is sliding on a surface, that surface will be exerting a force on the block. That force can be resolved into a component parallel to the surface (which we call the frictional component), and a component perpendicular to the surface (called the normal component). For many situations, we find experimentally that the frictional component is approximately proportional to the normal component. The frictional component divided by the normal component is defined to be a quantity called the coefficient of kinetic or sliding friction. The coefficient of kinetic friction obviously depends on the nature of the surfaces involved. The normal component on an object can be decreased if you pull in the direction of the normal component (the weight does not change). However pulling this way on the object not only decreases the normal component, but it also decreases the frictional component since they are proportional. This is why it is easier to slide something if you pull up on it while you push it. If you push down, the normal and frictional components increase so it is harder to slide the object. The weight of an object is the downward force exerted by Earth’s gravity on that object, and it does not change no matter how you push or pull on the object.

Micah knows that a car had a change in velocity of 15 m/s. What does micah need to determine acceleration.
katrin2010 [14]
The time component is needed. The acceleration is the change of velocity divided by the time in when this change of velocity happens.

What is the power of a machine that pushes with a force of 3 n for a distance of 9 m in 8 s?
dalvyx [7]
The work done by the machine is equal to the product between the force applied and the distance over which the force is applieds, so in this case:
W=Fd=(3 N)(9 m)=27 J

And the power of the machine is equal to the ratio between the work done by the machine and the time taken:
P= \frac{W}{t}= \frac{27 J}{8 s}=3.38 W
