Answer:isotopes
Explanation:Isotopes form when the number of neutrons and atomic number change except for the protons don't change
<em>Answer</em>
Force = 170 N
<em>Explanation</em>
First find the distance (d) travelled by the bulldozer.
Sin 35 = 15/d
d = 15/(sin 35)
= 26.15m
Now;
work done = force × distance.
4500 J = force × 26.15
dividing both sides by 26.15,
Force = 4500/26.15
= 172.07 N
Answer to two significant figures = 170 N
Question:
The flow of air caused by _____ and the Coriolis effect creates distinct _____ on Earth's surface.
Answer:
- Differences in heating
- Wind patterns
Explanation:
The flow of air caused by <u>variations in the rate at which the different parts are heated</u> up as well as the Coriolis effect combine to create distinct <u>wind patterns </u>on Earth's surface.
The Coriolis Effect is used to describe a "force" that causes things (like objects, planes, air currents) traveling long distances around the Earth to appear to bend as they move rather than in a straight line.

Answer:
0.345m
Explanation:
Let x (m) be the length that the spring is compress. If we take the point where the spring is compressed as a reference point, then the distance from that point to point where the ball is held is x + 1.1 m.
And so the potential energy of the object at the held point is:

where m = 1.3 kg is the object mass, g = 10m/s2 is the gravitational acceleration and h = x + 1.1 m is the height of the object with respect to the reference point

According to the conservation law of energy, this potential energy is converted to spring elastic energy once it's compressed

where k = 315 is the spring constant and x is the compressed length





x = 0.345 m or x = -0.263 m
Since x can only be positive we will pick the 0.345m
Answer:
C. It decreases
Explanation:
The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualizing the particles of gas in the container moving with a greater energy when the temperature is increased.
A common example is cooking gas when refilled, there is a perceptible change in the temperature of the cylinder.
