- Streams shape landforms through moving farther and lower inside the ground.

- Ice running downhill creates gaps in a mountain area.

- Soil erosion is created through wind plus rain.

It the same child has a velocity of 2 m/s half-way down the slide, what is his kinetic energy?

Pani-rosa [81]

Answer:

$\frac{1}{2} \times m \times {v}^{2} \\ \frac{1}{2} \times m \times {2}^{2} \\ 2 \times m$

I dont the child mass...you should substitute that value to (m)

then you can get your answer

A 1 kg object sits on the earth’s surface. What is the force of gravity between the object and the earth? (mass of the earth = 5

snow_lady [41]

Answer:

9.81N

Explanation:

the force of attraction is given by

F=GmM/R²

where m is mass of the body

M is mass of the earth

R is radius of the earth

G is the universal gravitational constant(6.67x10-¹¹)

hence we substitute the values in the formula.

If R = 20 Ω, what is the equivalent resistance between points A and B in the figure?

poizon [28]

Answer:

c. 70 Ω

Explanation:

The R and R resistors are in parallel. The 2R and 2R resistors are in parallel. The 4R and 4R resistors are in parallel. Each parallel combination is in series with each other. Therefore, the equivalent resistance is:

Req = 1/(1/R + 1/R) + 1/(1/2R + 1/2R) + 1/(1/4R + 1/4R)

Req = R/2 + 2R/2 + 4R/2

Req = 3.5R

Req = 70Ω
