There are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge. The mass of the electron in 1.0 C of charge remains the same as the mass of an electron, which is approximately 9.109 x 10⁻³¹ kg.
We may utilise the elementary charge, which represents the charge of a single electron, to calculate how many electrons are present in 1.0 C of charge. It is estimated that the elementary charge is 1.602 x 10-19 C.
Number of electrons = Charge ÷ Elementary charge
Number of electrons = 1.0 C ÷ (1.602 x 10⁻¹⁹ C)
Calculating the division:
Number of electrons ≈ 6.24 x 10¹⁸ electrons
Therefore, there are approximately 6.24 x 10¹⁸ electrons contained in 1.0 C of charge.
It is crucial to remember that the electron's mass is unaffected by the charge when considering the electron's mass in 1.0 C of charge. Regardless of the charge it carries, an electron has a mass of about 9.109 x 10⁻³¹ kg.
Thus, the mass of one electron, which is roughly 9.109 x 10⁻³¹ kg, remains constant in 1.0 C of charge.

If there are 6 coulombs of charge moving through a wire in 2 seconds. How many amps are moving through this wire?
Answer:
Current = 3 Amperes
Explanation:
Given the following data;
Quantity of charge = 6 C
Time = 2 seconds
To find how many amps are moving through this wire;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge = current * time
Substituting into the formula, we have;
6 = current * 2
Current = 6/2
Current = 3 Amperes

athlete running on a circular track of radius 5 m completes one round in 12 s. what its average speed and average displacement?
Average speed = total distance/time
That's 2.62 m/s .
You don't want average displacement. You want average velocity.
That's (displacement)/(time).
That's zero, because displacement = 0.
The displacement ‘s' of a point moving in a straight line is given by: s = 6t^2 + 5t – 5, ‘s' being in cm and ‘t' in s. The initial velocity of the particle is:
Answer:
the initial velocity of the particle is 5 cm/s
Explanation:
Given initial displacement as, s = 6t² + 5t - 5
s is measured in "cm"
t is measured in "seconds"
Velocity is the rate of change of displacement with time. Expressed as follows;
[tex]v = \frac{ds}{dt} = 12t + 5[/tex]
for initial velocity, time (t) = 0
v = 12(0) + 5
v = 5 cm/s
Therefore, the initial velocity of the particle is 5 cm/s

Answer:
water cycle show the continuous movement of water with in the earth and atmosphere
Explanation:
Hope this helps :)
The water cycle is the process through which water evaporates from the earth's surface, rises into the atmosphere, cools and condenses into rain or snow in clouds, and then falls back to the surface as precipitation. Water that falls on land gathers in rivers and lakes, soil, and porous rock strata, and much of it goes back into the seas to evaporate. Water flows in and out of the system.

If we keep on applying force on a material object, can it gain speed of light?
Answer:
As an object moves faster, its mass increases. ... Because masses approach infinity with increasing speed, it is impossible to accelerate a material object to (or past) the speed of light. To do so would require an infinite force.

A). 0.65
B). 0.53
C). 1.92
D). 1.88
Answer:
Explanation:
The formula for this is
[tex]n_1sin\theta_1=n_2sin\theta_2[/tex] where the index of refraction of air is 1.00. Filling in and solving for n2:
1.00sin(25) = n₂sin(13) and
1.00(.423) = n₂(.225) and
[tex]\frac{1.00(.423)}{.225}=n_2[/tex] so
[tex]n_2=1.88[/tex], choice D.

A 150 g baseball is thrown with a speed of 20 m/s. After the ball hits the bat, the ball moves 40 m/s.
What is the momentum before it hits the bat?
What is the momentum after it hits the bat?
Answer:
3000 kg*m/s
6000 kg*m/s
Explanation:
p = m*v

Answer:
(C) 700 N
Explanation:
The given parameters are;
The mass of the mountain climber, m = 100 kg
The angle formed by the rope with the horizontal, θ = 45°
The gravitational field strength, g = 10 N/kg
The weight of the man, W = m × g
∴ W = 100 kg × 10 N/kg = 1,000 N
At equilibrium, we have;
The downward force, the weight of the man, W = The upward force, the vertical component of the tension on the two halves of the rope
We have;
W = T × sin(θ) + T × sin(θ)
∴ 1,000 N = 2 × T × sin(45°)
Therefore, we have;
T = 1,000 N/(2 × sin(45°)) = 707.106781 Newtons
Therefore, the tension in the rope is closest to (approximately) 700 N.

Explanation:
Given:
Number of resistors = 2 (10 ohm each)
Series of resistors
EMF = 10 volt
Find:
Current in the circuit(I)
Computation:
Total resistance in series = R1 + R2
Total resistance in series = 10 + 10
Total resistance in series = 20 ohm

The angle at which the refracted light ray lies
along the boundary of the two mediums, this
is the definition of
Answer:
Critical angle
Explanation:
The angle of incidence when the refracted angle is 90°; we have the critical angle at this point. At this point, the refracted ray lies between the boundary between the two medium, this is the angle just before total internal reflection occurs, as the refracted angle exceeds 90°, all rays are reflected. Hence, we can conclude that it is the largest angle at which reflection can still occur.

what type of object is called object at rest ? Write with example.
Answer:
ln physics, Rest is the state at which an object is stationary or not moving with respect to its surroundings, and is said to be at rest. An example would be a book lying on a table.
Answer:
When an object does not change it's position with respect to time it is said to be at rest.
Explanation:
Example- A person sitting on a chair or a book lying on a table.
Please note there is no such thing as absolute rest.
Take the example of a person A sitting in a moving bus. If the observer is in the bus then to him person A is at rest. However if the observer is is outside the bus then person A is in motion as the bus is moving.
