Two men are standing on a frictionless ice surface holding opposite ends of a rope. One man (mass = 80 kg) pulls on the rope wit

ankoles [38]

Answer:

The acceleration of man 1 and 2 is $3.125\ m/s^2$ and $4.167\ m/s^2$ .

Explanation:

Mass of man 1, m₁ = 80 kg

Mass of man 2, m₂ = 60 kg

One man pulls on the rope with a force of 250 N.

Let a₁ is acceleration of man 1,

F = m₁a₁

$a_1=\dfrac{F}{m_1}\\\\a_1=\dfrac{250}{80}\\\\a_1=3.125\ m/s^2$

Let a₂ is acceleration of man 1,

F = m₂a₂

$a_2=\dfrac{F}{m_2}\\\\a_2=\dfrac{250}{60}\\\\a_2=4.167\ m/s^2$

So, the acceleration of man 1 and 2 is $3.125\ m/s^2$ and $4.167\ m/s^2$ .

He instruction booklet for your pressure cooker indicates that its highest setting is 11.1 psi . you know that standard atmosphe

blagie [28]

Given that,

Atmospheric Pressure = 14.7 psi

Cooking Pressure = 14.7 +11.1 = 25.8 psi

Take, Atmospheric Temperature = 25 °C

Cooking Temperature = ??

Since, we know that Gas equation is given by:

PV = nRT

P ∝ T

P1 / T1 = P2 / T2

14.7/ 25 = 25.8/ T2

T2 = 25*25.8/14.7

T2 = 43.87 °C

The cooking pressure will be 43.87 °C.

Describe how energy from the sun interact with substances

bagirrra123 [75]

Answer:

substances will move faster and become warm to the touch.

Explanation:

when the radiation from the sun comes down and hits substances, the substances absorbs the radiation making them warm. the absorbed energy is transformed into heat energy. this heat energy plays an important role in regulating the temperature of the Earths crust, surface waters, and low atmosphere.

Which type of motion does a wooden block NOT have when sliding down a hill? Question 1 options: A. Vibrational B. Rotational C.

nlexa [21]

Answer - the correct option is option B rotational

Explanation-

A block that is sliding Downloads on inclination can have vibrational movement due to certain ups and downs or inequalities on on the surface. It will have frictional force due to the aberrations present in the surfaces of both block and Road and it will have transitional motion acting as the block's position is changing from one point to another the only motion.

It doesn't have is rotational because rotational movements happen with circular objects only.
