Average speed = (total distance) / (total time to cover the distance)
= (90km + 60km) / (1hr + 3hr)
= (150 km) / (4 hr)
= 37.5 km/hr .
<span>It is true that all nuclear energy results in
the rapid release of energy, such as in atomic bombs. <span>A process wherein the atom’s nucleus
is further divided into two nuclei, that is, fission products, is called
nuclear fission. This happens when the nuclei of radioactive elements (e.g.
Uranium or Plutonium isotopes) are able to attract neutrons. Because these
isotopes’ nuclei are unstable, an addition to their energy causes them to
divide into new pieces of neutron. In nuclear reactors, fission occurs when the
power plant gathers heat from a steam in a physical process. Nuclear reactors
are designed to sustain nuclear chain reactions.</span></span>
<span> <span> The answer to your question is: increase the force applied to the object.
Two items are provided as a basis for that conclusion:
1. According to Newton's Second Law of Motion, the formula for finding force is: F = ma
where F is the force,
m is the mass of an object,
and a is the acceleration of the object.
And 2: work = force x distance or W = F x d.</span></span>
No, according to many pictures taken in space, the moon is white. However, on rare occasions, the moon appears blue.
Hope this helps! ☺♥
Answer:
Impulse = 322.5[kg*m/s], the answer is D
Explanation:
This method it is based on the principle of momentum and the amount of movement; and used to solve problems involving strength, mass, speed and time.
If units of the SI are used, the magnitude of the impulse of a force is expressed in N * s. however, when remembering the definition of the newton.
Now replacing the values on the following equation that express the definition of impulse
![Impulse = Force * Time\\\\Impulse = 215 * 1.5 = 322.5 [kg*m/s]](https://tex.z-dn.net/?f=Impulse%20%3D%20Force%20%2A%20Time%5C%5C%5C%5CImpulse%20%3D%20215%20%2A%201.5%20%3D%20322.5%20%5Bkg%2Am%2Fs%5D)
