If scientist were given the power to do what they wanted to do almost everyone would be lab rats

We discover new things every day which we need to test to see how it helps humans. Sometimes humans are needed for the test .

For example the Russian sleep experiment was a very terrible incident because humans were used.

Some scientist are ma* (forgive my use of foul words)  and will go to any length just to make and prove their discoveries

The correct graph that represents the power P dissipated by the resistor as a function of its the resistance R is Graph B.

According to Ohm's law, the voltage V across a resistor is equal to the product of the current I through the resistor and the resistance R of the resistor:
V = I*R

The power P dissipated by the resistor is equal to the product of the voltage V across the resistor and the current I through the resistor:
P = V*I

Substituting the equation for voltage from Ohm's law into the equation for power gives:
P = (I*R)*I = I^2*R

Since the voltage source is constant, the current I through the resistor is inversely proportional to the resistance R of the resistor:
I = V/R

Substituting this equation for current into the equation for power gives:
P = (V/R)^2*R = V^2/R

This equation shows that the power P dissipated by the resistor is inversely proportional to the resistance R of the resistor. Therefore, the graph of power P versus resistance R is a hyperbola, as shown in Graph B.

Answer:

Power of 5 watts is used

Explanation:

Mechanical Work and Power

Mechanical work is the amount of energy transferred by a force.

Being F the force vector and s the displacement vector, the work is calculated as:

\(W=\vec F\cdot \vec s\)

If both the force and displacement are parallel, then we can use the equivalent scalar formula:

W=F.s

Power is the amount of energy converted per unit of time. The SI unit of power is the watt, equal to one joule per second.

The power can be calculated as:

\(\displaystyle P=\frac {W}{t}\)

Where W is the work and t is the time.

It's required to calculate the power used in t=30 seconds when W=150 Joules of work are completed. Substitute in the formula:

\(\displaystyle P=\frac {150}{30}\)

P = 5 Watt

Power of 5 watts is used

The mass of Car B is -6000 kg.

To solve this problem, we can apply the principle of conservation of momentum, which states that the total momentum before the collision is equal to the total momentum after the collision.

Therefore, we can write the equation for the conservation of momentum as:

(mass of Car A * velocity of Car A) + (mass of Car B * velocity of Car B) = (mass of Car A + mass of Car B) * velocity after collision

Let's substitute the given values into the equation:

(2000 kg * 10 m/s) + (mass of Car B * 0 m/s) = (2000 kg + mass of Car B) * (-5 m/s)

Simplifying the equation:

20000 kg*m/s = -5 m/s * (2000 kg + mass of Car B)

Dividing both sides by -5 m/s:

-4000 kg = 2000 kg + mass of Car B

Subtracting 2000 kg from both sides:

mass of Car B = -4000 kg - 2000 kg

mass of Car B = -6000 kg

A normal force is a force applied perpendicular to a surface on an object in contact with it. The weight is the gravitational force imposed on an object, and it is equal to the mass multiplied by the acceleration due to gravity.

When an object is put on a scale at rest on a level surface, the normal force equals the weight. In this instance, the normal force acting upwards from the scale on the object is equal to the weight acting downwards.

Here are two instances of normal forces that are not equal to weight:

When a person stands on an inclined plane or ramp, the normal force applied by the plane is less than the person's weight, because some of the weight is resolved parallel to the plane, causing the person to slide down if enough friction exists.

The normal force exerted by the air or other medium on a person in free fall is zero, while their weight due to gravity stays constant.

The earthquake would occur 13 minutes before 10:05 a.m. which will be at 9.52 am.

The p-waves travel with a constant velocity of 7 km/s

The time can be calculated by using the formula

t = d / v

where

T1 =  10:05 a.m

d is the distance they take to travel from the epicenter

v is the speed of the p-waves

On average, the speed of p-waves is

v = 7 km/s

d = 5600 km (given)

Substituting the values in the formula;

t = d / v

t = 5600 ÷ 7

t = 800 seconds

Converting into minutes,

t = 800 ÷ 60

t = 13.3

≈ 13 mins

T1 -  13 mins = T2

10:05 - 13 mins = 9.52 am

It means the earthquake occurred prior 13 minutes, that is at 9.52 am.

Therefore, the earthquake occurred at 9.52 am.

The full load primary current of a 230/115V, 2kVA transformer can be calculated using the formula:

I_primary = (2kVA * 1000 VA/kVA) / (230V)

I_primary = 8.7V

The full load secondary current of the transformer can be calculated using the formula:

I_secondary = (2kVA * 1000 VA/kVA) / (115V)

I_secondary = 17.4V

Therefore, the full-load primary current of the transformer is approximately 8.7V, and the full-load secondary current is approximately 17.4V. It is important to note that these values are based on the assumption that the transformer is operating at its full load capacity. If the transformer is operating at a lower load, the primary and secondary currents will be correspondingly lower.

Answer:

31.25m

Explanation:

using the formula

\(v {}^{2} = u {}^{2} + 2as\)

where v = final velocity = 0

u = initial velocity = 25

a = acceleration = -10 as its thrown upwards

s = distance (max height) = ?

rearranging the equation to find s:

\(s = \frac{ {v}^{2} - {u}^{2} }{2a} \)

\(s = \frac{0 {}^{2} - (25) {}^{2} }{2( - 10)} = 31.2m\)

Answer:

61.33 Kg

Explanation:

From the question given above, the following data were obtained:

Distance = 1×10² m

Time = 9.5 s

Kinetic energy (KE) = 3.40×10³ J

Mass (m) =?

Next, we shall determine the velocity Leroy Burrell. This can be obtained as follow:

Distance = 1×10² m

Time = 9.5 s

Velocity =?

Velocity = Distance / time

Velocity = 1×10² / 9.5

Velocity = 10.53 m/s

Finally, we shall determine the mass of Leroy Burrell. This can be obtained as follow:

Kinetic energy (KE) = 3.40×10³ J

Velocity (v) = 10.53 m/s

Mass (m) =?

KE = ½mv²

3.40×10³ = ½ × m × 10.53²

3.40×10³ = ½ × m × 110.8809

3.40×10³ = m × 55.44045

Divide both side by 55.44045

m = 3.40×10³ / 55.44045

m = 61.33 Kg

Thus, the mass of Leroy Burrell is 61.33 Kg

The moment of force is 40 Nm here. The displacement is 2.5 m and the angle of inclination is 45°. The force about the pivot is then 28.2 N.

Moment of force is the product of the force and distance from a fixed axis. Moment of force can be calculated for both balanced and unbalanced forces.

The expression for moment of force relating the distance d and force f with an angle of inclination θ is written as below:

moment of force =  f d sin θ

Given that moment of force = 40 Nm

distance from the fixed axis from the figure =  2 m

angle of inclination = 45 °

40 Nm =   2 f sin 45.

20 = f sin 45

  f = 20 N / sin 45
