A runoff
Explanation: A runoff is when frozen water melts so if it falls down a mouantan there probably melting ice hope this helps :} pls give brainlest
John is hiking and notices a small stream of water flowing down the side of the mountain. In this John is experiencing runoff of the water cycle. Thus, the correct option is A.
What is Runoff?Surface runoff is the flow of water which is occurring on the ground surface when there is excess rainwater, storm water, melt water, or other sources of water, which can no longer sufficiently rapidly infiltrate in the soil of the region.
Runoff occurs in the excessive rainwater and it saturates the ground surface. Rivers and lakes are the results of water runoff. There is some evaporation from the water runoff into the atmosphere however for the most part water in the rivers and lakes returns back to the oceans.
Therefore, the correct option is A.

A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is her acceleration? Is the acceleration higher of another cyclist who accelerates from 0 to 30 m/s in 8 seconds? How do you know?
Answer:
Acceleration of one cyclist=[tex]2.67m/s^2[/tex]
Yes, the acceleration is higher of another cyclist who accelerates from 0 to 30 m/s in 8 seconds.
Explanation:
We are given that
Initial velocity of one cyclist, u=0 m/s
Final velocity of one cyclist, v=8m/s
Time, t=3 s
Initial velocity of another cyclist, u'=0
Final velocity of another cyclist, v'=30m/s
Time, t'=8 s
We know that
Acceleration, [tex]a=\frac{v-u}{t}[/tex]
Using the formula
[tex]a=\frac{8-0}{3}=\frac{8}{3}=2.67m/s^2[/tex]
Acceleration of one cyclist=[tex]2.67m/s^2[/tex]
Acceleration of another cyclist, a'=[tex]\frac{30-0}{8}m/s^2[/tex]
Acceleration of another cyclist, a'=[tex]3.75m/s^2[/tex]
Yes, the acceleration of another cyclist is higher than the cyclist which accelerates from 0m/s to 8m/s.

Discuss how the motion of the stunt cyclist relates to the forces acting on the stunt cyclist during the collision
Answer:
hello your question is incomplete hence I will give you a general answer on how a stunt cyclist performs his stunts successfully
answer ;
The stunt cyclist trying to perform some sort of stunt with the bicycle will be faced with some forces like the static fiction between the tires of the bicycle and wall and also a centripetal force.
In order to overcome the centripetal force the minimal grip of the bicycle must be equal to the weight and the speed at which the cyclist must go can be represented as :
[tex]V_{min} = \sqrt{\frac{r.g}{u} }[/tex]

You have two lens A and B of focal length +50cm and -50cm respectively. The nature and power of the lenses respectively isa. Concave, -2 D ; Convex, +2 D b. Convex, +2 D; Concave, - 2 D
Answer:
Concave, +2D
Convex -2D
Explanation:
Power of a lens is the reciprocal of its focal length.
For lens of +50cm = 0.5m
Power of the lens = 1/0.5
Power of the lens = +2Dioptres
Since the focal length is positive, the lens is concave
For the lens of -50cm = -0.5m
Power = 1/-0.5
Power = -2D dioptres
Since the focal length is negative, the lens is convex
A 12 kg object speeds up from an initial velocity of 10 m/s north to a final velocity of 15 m/s north. Calculate the change in momentum
Answer:
60m/s
Explanation:
momentum = Mass × Velocity
Initial Momentum = 12 × 10
= 120
Final Momentum = 12×15
=180
Change in Momentum = 180 - 120
= 60m/s
Answer:
60Explanation:
formula for change in momentum = F =∆p/∆t
F∆t = ∆p
∆p = m(v - Vo)
∆p = 12(15-10)
=12(5)= 60

How are humidity and precipitation related?
A. When humidity is low, the chance of precipitation is high.
b.When humidity is high, the chance of precipitation is high.
c.When humidity is high, the chance of precipitation is low.
d.Changes in humidity do not cause precipitation.
Answer:
Relative humidity depends on the amount moisture actually in the air at some temperature to the amount of moisture that the air can hold.
For instance, at 25 deg C the air has a saturation pressure of 23.76 mm of Hg.
That means that if at that temperature the pressure of the water vapor in the air reaches 23.76 mm Hg then the air is 100% saturated.
I believe the standard air pressure at 25 deg C is 760 mm Hg.
Now if the pressure of the water vapor in the air is 1/2 * 23.76 = 11.88 mm then the air is 50% saturated and the relative hunidity is 50 %.
At 100% relative humidity rain occurs (the air can't hold any more water).
When humidity is high, the chance of precipitation is high. The correct answer is b. When humidity is high, the chance of precipitation is high.
The amount of moisture or water vapor in the air is referred to as humidity. Relative humidity is a common way to measure it since it shows how much moisture the air is holding relative to how much it could contain at a particular temperature.
Any type of water that falls from the atmosphere and makes it to the surface of the Earth is referred to as precipitation. Examples include rain, snow, sleet, and hail.
When humidity levels are high, there is a lot of moisture in the air, which increases the possibility that saturation will occur. Excess water vapor condenses into visible water droplets or ice crystals as the air gets saturated, creating clouds. Condensed moisture in the clouds eventually gains enough weight to return to Earth as precipitation.
Therefore, when humidity is high, the chance of precipitation is high. The correct answer is:
b. When humidity is high, the chance of precipitation is high.
