Answer:
False
Explanation:
Neither the USGS nor any other scientists have ever predicted a major earthquake. USGS scientists can only calculate the probability that a significant earthquake will occur in a specific area within a certain number of years.
Answer:
hypernova making a black hole, and merger of two neutron stars
When the player strikes the ball, kinetic energy is at its greatest.
Kinetic energy = 1/2*m*
where m denotes mass and v denotes velocity.
Therefore, kinetic energy is inversely correlated with square of velocity.
When a player strikes the ball, velocity is at its highest.
Thus, when the player strikes the ball, kinetic energy is at its highest.
<h3>What is kinetic energy?</h3>
It is the energy that a body has because it is moving.
<h3>Which 5 forms of kinetic energy are there?</h3>
Kinetic energy comes in five different forms:
- radiant
- thermal
- sound
- electrical
- mechanical.
Kinetic energy is measured in Joules.
Importance of kinetic energy:
- The capacity to perform work is kinetic energy's most significant quality.
- Force acting on an object while it is moving is referred to as work.
- Energy and work are interchangeable because of their tight relationship.

<span> 1.the atom has 7 neutrons and 8 protons....
because the positively charged particles are the protons ...and 8 is also the atomic number ...so number of neutrons can be calculated by subtracting </span>atomic number from the mass number...which gives us the neutrons 7 ...
Hope it helps !!!
Let car A's starting position be the origin, so that its position at time <em>t</em> is
A: <em>x</em> = (40 m/s) <em>t</em>
and car B has position at time <em>t</em> of
B: <em>x</em> = 100 m - (60 m/s) <em>t</em>
<em />
They meet when their positions are equal:
(40 m/s) <em>t</em> = 100 m - (60 m/s) <em>t</em>
(100 m/s) <em>t</em> = 100 m
<em>t</em> = (100 m) / (100 m/s) = 1 s
so the cars meet 1 second after they start moving.
They are 100 m apart when the difference in their positions is equal to 100 m:
(40 m/s) <em>t</em> - (100 m - (60 m/s) <em>t</em>) = 100 m
(subtract car B's position from car A's position because we take car A's direction to be positive)
(100 m/s) <em>t</em> = 200 m
<em>t</em> = (200 m) / (100 m/s) = 2 s
so the cars are 100 m apart after 2 seconds.
