How could rescue workers use squeezing or compressing to get energy to their flashlights during rescue missions?

Answer:

4.395kg

Explanation:

1kg=1000g

Therefore, 4395g/1000g=4.395kg

Answer:

3000 Kg.m/s

Explanation:

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

Mass (m) of shark = 200 Kg.

Velocity (v) of shark = 15 m/s.

Momentum of shark =..?

The momentum of an object is simply defined as the product of the mass and velocity of the object. Mathematically, it is expressed as:

Momentum = mass (m) × velocity (v)

With the above formula, we can obtain the momentum of the shark as follow:

Mass (m) of shark = 200 Kg.

Velocity (v) of shark = 15 m/s.

Momentum of shark =..?

Momentum = mass (m) × velocity (v)

Momentum of shark = 200 × 15

Momentum of shark = 3000 Kg.m/s

Therefore, the momentum of the shark is 3000 Kg.m/s.

Answer:

The correct answer to the physics problem in pressure given above would be 1.5 N.

First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).

Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)  

Consequently, I used the equation of pressure (P = Force/Area).

P = 461.58 N / .00314 m^2

P = 1.47 or 1.5 N

Explanation:

The time taken by the boulder to hit the ground with velocity of 45 m/sand distance of 20 m is 0.44 m/s.

Velocity is defined as the speed at which an object's position changes in relation to time and a frame of reference.

It can also be defined as the direction of an object's motion as a measure of how quickly its position is changing as seen from a certain point of view and It is measured by a specific unit of time.

There are basically four types of velocity.

Velocity can be expressed as

Velocity = Distance / Time

Time = Distance / velocity

Time = 20 m / 45 m/s

Time = 0.44 m/s

Thus, the time taken by the boulder to hit the ground with velocity of 45 m/sand distance of 20 m is 0.44 m/s.

Answer:

cm/s2 (cm per second squared)Explanation:

Given :

A constant volume of gas at 1.00 atm is heated from 30.0°C to 40.0°C.

To Find :

The pressure change.

Solution :

By Gay-Lussac's Law :

[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\\dfrac{1}{30+273}=\dfrac{P_2}{40+273}\\\\P=\dfrac{313}{303}\\\\P=1.033\ atm[/tex]

Change in pressure,

[tex]\Delta \ P=P_2-P_1\\\\\Delta \ P=(1.033-1)\ atm\\\\\Delta \ P=0.33\ atm[/tex]

Therefore, the pressure change is 0.33 atm.

Hence, this is the required solution.

The change in pressure when a constant volume of gas at 1.00 atm is heated from 30.0°C to 40.0°C is 0.033 atm and this can be determined by using the Gay-Lusac's law.

Given :

Gay-Lussac's law can be used in order to determine the pressure change when a constant volume of gas at 1.00 atm is heated from 30.0°C to 40.0°C.

According to Gay-Lusac's law:

[tex]\rm \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

Now, substitute the values of the known terms in the above expression.

[tex]\rm \dfrac{1}{30+273}=\dfrac{P_2}{40+273}[/tex]

Simplify the above expression in order to determine the value of [tex]\rm P_2[/tex].

[tex]\rm P_2 = \dfrac{313}{303}=1.033\;atm[/tex]

Now, the change in pressure is given by:

[tex]\rm \Delta P = P_2-P_1[/tex]

[tex]\rm \Delta P = 1.033-1=0.033\;atm[/tex]

Therefore, the change in pressure when a constant volume of gas at 1.00 atm is heated from 30.0°C to 40.0°C is 0.033 atm.

Answer:

200 N

Explanation:

Assume that counterclockwise is positive and clockwise is negative.

The 500 N load is 0.5 m from the fulcrum, so the effort force F on the other end is 1.25 m from the fulcrum.

Sum of the torques about the fulcrum equal 0.

∑τ = Iα

(500 N) (0.5 m) − F (1.25 m) = 0

F = 200 N

Answer:

-0.8 m/s²

Explanation:

Acceleration is the slope of a velocity vs. time graph.

Things that are atomic in size.

Explanation:

Atomic force microscopes have advanced to the point that scientists can observe details resolved to a few picometers (or the size of atoms).

The observations that can be made with atomic force microscopes are the things that are atomic in size, therefore the correct answer is option A.

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

A length, for instance, is a physical quantity. A defined, predetermined length is represented by the length unit known as the meter.

The atomic force microscope is used to observe things, that are very small and comparable to the atomic in size.
