Answer: 2812500 joules
Explanation:
Mass of car = 1500kg
Velocity of car = 75mph
Kinetic energy = ?
Recall that kinetic energy is the energy possessed by a moving object, and it depends on its mass M and velocity, V
Thus, Kinetic energy = 1/2 x mv^2
= 1/2 x 1000kg x (75mph)^2
= 0.5 x 1000kg x (75mph)^2
= 500 x 5625
= 2812500 joules
Thus, the car travels with a kinetic energy of 2812500 joules
Answer:
NO
Explanation:
if it has no acceleration then it's not moving
1. Scientists are responsible for removing plasmids, small rings of DNA, from bacterial cells.
2. The Enzymes cut open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome.
3. The human insulin gene attaches the open ends of the plasmid to form a closed ring.
4. Some bacterial cells take up the plasmids that have the insulin gene.

5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.</span>
Answer:
Explanation:
The frequency equation is
where f is frequency measured in Hz, v is velocity of sound measured in m/s and 
is wavelength measured in meters. Filling in our given info:
and
so
(That is the incorrect number of sig dig's by the way. It should only be 2 since the number 340 only has 2 sig dig's)
Regardless of where the cars are in the loop, centripetal force is always directed toward the center of rotation. So even if a car you're riding in is at the top of a loop, upside-down, you will feel pressed into your seat.
