solution:
here,
mass(m)=10 kg
acceleration due to gravity(g)=50
height(h)=10
we know,
potential energy(p.e)=m*g*h
=10*50*10
=5000
the potential energy is 5000.
Answer:
No.
Explanation:
If the so called Dinosaurs died from an asteroid but yet the species of DOGS lived, I'm sure humans can live.
Answer:
B. A device that absorbs and draws heat from a hot object,
dispersing it into the surroundings
Explanation
a heat sink is an object that disperses heat from another object. They're most commonly used in computers, but are also found in cell phones , DVD players and even refrigerators. In computers, a heat sink is an attachment for a chip that prevents the chip from overheating and, in modern computers, it's as important as any other component.
Answer:
B. the air pressure decreases
Explanation:
As elevation increases, there is less overlying atmospheric pressure mass, so that atmospheric pressure decreases with increasing elevaton.
Answer:
C ) 1500 Joules
Explanation:
In the attached image, we can see how the box was moved 10 meters by the force of 150 N.
The definition of work is W = F * d
therefore
W= 150*10 = 1500 J
