ivanzaharov [21]2 years ago
6 0

As we know,

\boxed{ \boxed{ \:  \: velocity =  \frac{displacement}{time} \:  \:  }}

so, let's solve for velocity (v)

  • v =  \dfrac{528.0}{4.0}

  • v = 132 \:  \: m {s}^{ - 1}

denpristay [2]

Answer:

25100A

Explanation:

t= 1ms = 0.001s

q = 25.1C

From the relationship between charge and current , the charge is equal to the product of current and time

q = i×t

Where q = charge

i = current

t = time

i = q/t = 25.1/0.001

i = 25100A.

vodomira [7]

The reason why Kim's hair rises and sticks out is due to electrostatic attraction.

<h3>What is charging by friction?</h3>

We know that one of the ways in which a body is able to acquire static charges is by friction. When a body is rubbed against another, there could be loss or gain of charges leaving a net charge on each body.

The process that occurs when some of Kim's hair rises and sticks out toward the balloon, even though the balloon hasn't touched her hair is electrostatic attraction.

If earth's mass were half its actual value but its radius stayed the same, the escape velocity of earth would be:________
siniylev [52]

If the earth's mass were half its actual value but its radius stayed the same, the escape velocity of the earth would be V_e = \sqrt{\dfrac{GM}{r}}.

<h3>What is an escape velocity?</h3>

The ratio of the object's travel distance over a specific period of time is known as its velocity. As a vector quantity, the velocity requires both the magnitude and the direction. the slowest possible speed at which a body can break out of the gravitational pull of a certain planet or another object.

The formula to calculate the escape velocity of earth is given below:-

V_e=\sqrt{\dfrac{2GM}{r}}

Given that earth's mass was half its actual value but its radius stayed the same. The escape velocity will be calculated as below:-

V_e=\sqrt{\dfrac{2GM}{r\times 2}}

V_e = \sqrt{\dfrac{GM}{r}}.

Therefore, If the earth's mass were half its actual value but its radius stayed the same, the escape velocity of the earth would be V_e = \sqrt{\dfrac{GM}{r}}.
