When a honeybee flies through the air it develops a charge of +20pC, the electrons lost during the process of acquiring this charge is 1.25×10⁸ electrons.

Use an atom's atomic number and mass number to determine how many subatomic particles are present in it: Atomic number = number of protons. Atomic number = number of electrons. Mass minus atomic number equals the quantity of neutrons.

The honeybee's charge

Q = 20 pC = 20 × 10⁻¹² C

The current equation for the number of electrons is

n = Q/e

Where;

e is charge on electron = 1.6 × 10⁻⁻¹⁹ C

The mass of the skateboard by conservation of momentum will be 2.84 kg.

Momentum can be defined as the force behind a body's motion.

Momentum is measured by "mass velocity" since it depends on both the speed and the direction of the body's motion. Since velocity is a vector and mass is a scalar, momentum is a vector quantity.

skateboard mass is 2.84 kg.

m1 =  student mass  = 45.5 kg

m2= skateboard  Mass

u = student Velocity = 4.25 m/s

v = student and skateboard velocity = 4 m/s

As momentum is conserved we have

m1*u=m1*v+m2*v

m2=(m1u-m1v)/v

m2=(45.5*4.25-45.5*4)/4

The current flowing through the heating element is about 104.35A.

Ohm's Law states that the current (I) flowing through a circuit is equal to the voltage (V) divided by the resistance (R).

I = V / R

We know the resistance of the heating element is 11.5 ohms. We can use the power rating of the kettle, which is 1200W, to calculate the voltage. Power is equal to voltage multiplied by current, so we can use this equation to find the voltage:

P = V * I

V = P / I

We can substitute the known values into this equation:

V = 1200 / I

Now we can use Ohm's Law to find the current:

I = V / R

Substituting the values we know:

I = (1200 / I) / 11.5

Solving for I, we get:

I = 104.35A

The current flowing through the heating element is about 104.35A.

The wall exerts a greater force on the ball when it hits and sticks to the wall. This is because in this case, the wall is exerting a static force on the ball, while in the other case, the wall is exerting a dynamic force on the ball as it rebounds.

what is force ?

Force is a physical quantity that can be described as an action or influence that causes a change in an object's motion, direction, shape, or energy. It can be measured in terms of energy per unit of time, or momentum per unit of time. Force can be applied to an object by another object, and can also be applied by a person.

Force can be exerted by an object when it is acted upon by another object, such as when a person pushes a door open. Force can also be exerted by a person, such as when a person kicks a ball. Force can be either attractive or repulsive, and can cause objects to move, stop, or accelerate. Forces can be caused by contact between two objects, or by the application of a field of force, such as gravity or electrostatic forces.

The velocity of the truck after the collision is 5.6 kmph.

The rate at which an object's position changes when observed from a specific point of view and when measured against a specific unit of time is known as its velocity.

The velocity of the truck after the collision can be calculated using the conservation of momentum principle. The principle states that the total momentum of an isolated system remains constant if no external forces act on it.

Momentum is calculated as mass * velocity (p = m * v)

Before the collision, the momentum of the car is m1 * v1 = 400 kg * 72 kmph = 28800 kgkmph

and the momentum of the truck is m2 * v2 = 4000 kg * 9 kmph = 36000 kgkmph

After the collision, the momentum of the car is m1 * v'1 = 400 kg * 18 kmph = 7200 kg*kmph

Now we use the principle of conservation of momentum to find the velocity of the truck after collision.

momentum before collision = momentum after collision

m1 * v1 + m2 * v2 = m1 * v'1 + m2 * v'2

28800 + 36000 = 7200 + m2 * v'2

64800 = 7200 + m2 * v'2

v'2 = (64800 - 7200) / 4000 = 5.6 kmph

Therefore, the velocity of the truck after the collision is 5.6 kmph.

The spring constant, also known as the rate or stiffness of the spring, is a measure of the force required to compress or extend a spring by a certain distance. It is defined as the change in force per unit change in length of the spring. The spring constant is usually denoted by the letter k and has units of force per unit length (such as N/m or lbf/in).

The magnitude of the electric field strength between the two parallel conducting plates is 75 V/cm.

What is magnitude?

The magnitude of a quantity refers to the size or amount of that quantity, regardless of its direction. For example, the magnitude of velocity is the speed at which an object is moving, regardless of the direction it is moving in. Similarly, the magnitude of electric field is the strength of the field, regardless of the direction of the field.

To calculate the electric field strength between the two parallel conducting plates, we can use the formula:

E = V / d

where E is the electric field strength, V is the potential difference, and d is the distance between the plates.

Given that the potential 6.0 cm from the zero volt plate is 450 V, we can use this information to calculate the electric field strength between the plates:
