Examples of man made objects that spread an impulse over a large amount of time

Example of object that spread an impulse over a large amount of time: airbag

Explanation:

The impulse exerted on a body during a collision is defined as the product between the force exerted on the body and the duration of the collision:

I=F \Delta t

where

I is the impulse

F is the average force

\Delta t is the duration of the collision

Also, the impulse is equal to the change in momentum of the body:

I=\Delta p

Therefore

\Delta p = F \Delta t

Which can be rewritten as

F=\frac{\Delta p}{\Delta t}

Assuming that the change in momentum in the collision is constant, this means that the force exerted on the body is inversely proportional to the duration of the collision: therefore, the larger the time, the smaller the force exerted.

The purpose of the airbag is indeed to increase the duration of the collision, \Delta t: this way, the force experienced by the driver during a car accident will be smaller.

A 12.0 V car battery is being used to power the headlights of a car. Each of the two headlights has a power rating of 37.7 Watts
marshall27 [118]

Answer:

3.921*10^19 electrons

Explanation:

To find the number of electron that trough the car battery you first calculate the current by using the following formula, which relates the power with the voltage:

P=IV          (1)

P: power of both headlights = 2(37.7W) = 75.4 W

I: current = ?

V: voltage of the battery = 12.0 V

You solve the equation (1) for I:

I=\frac{P}{V}=\frac{75.4W}{12.0V}=6.283A=6.238\frac{C}{s}

Next, you use the equivalence 1C = 6.241*10^18 electrons:

6.238\frac{C}{s}*\frac{6.241*10^{18}\ electrons}{1C}=3.921*10^{19}\ electrons/s

The number of electrons that cross the battery per second is 3.921*10^19 electrons

in order to generate electricity, nuclear powerplants take advantage of this part of the electromagnetic spectrum

Bit of an odd question. Power Plants are known to use water-powered turbines to generate electricity, but can also make use of nuclear fission.

How does a generator use the effect you noticed in the pickup coil to generate electrical energy? What energy transformations ar
Oksana_A [137]

Answer:

Movement of Electrons in opposite direction of the rotation of the pickup coil leads to the direction of Electrical energy ( Alternating current ).

Explanation:

For a Generator to generate electricity, Electrons that is found in the rotating coil of the Generator will experience some sort of force that makes them to start moving in a direction that is perpendicular to the direction of the rotating/pickup coil found in the Generator.

The conversion of mechanical energy (Rotation of the pickup coil ) to electrical energy takes place in the Generator

The generator makes an alternating current because electrons move in opposite direction of the rotating coil

In other to generate a Direct current using a generator we have to replace the slip rings with commutator.

The student throws one cannonball directly upward at 5.0 m/s and simultaneously throws the other cannonball directly downward at
Mademuasel [1]
Let the cannonball be thrown at a height of h above ground.
Then  the potential energy of the ball is
V = m*g*h
where
m = the mass of the ball
g = 9.8 m/s²

Also, the kinetic energy of the ball is
K = (1/2)mu²
where
u = 5 m/s, the vertical launch velocity.
Ignore wind resistance.

Because the total energy is preserved, the total energy (n the form of only kinetic energy) when the ball strikes the ground is
(1/2)mV²
where V = vertical velocity when the ball strikes the ground.

Expressions for both the initial and final energy are equal regardless of whether the ball s thrown downward or upward.
Therefore there is no difference in the landing speed. 

Answer: There is no difference.
