3. A bicycle has a momentum of 25.00 kg* m/s and a velocity of 2.5 m/s . What is the bicycle's
Anna35 [415]

Answer:

10 kg

Explanation:

The question is most likely asking for the mass of the bicycle.

Momentum is the product of an object's mass and velocity. Mathematically:

p = m * v

Where p = momentum

m = mass

v = velocity

Hence, mass is:

m = p / v

From the question:

p = 25 kgm/s

v = 2.5 m/s

Mass is:

m = 25 / 2.5 = 10 kg

The mass of the bicycle is 10 kg.

In case the question requires the Kinetic energy of the bicycle, it can be gotten by using the formula

K. E = ½ * p * v

K. E. = ½ * 25 * 2.5 = 31.25 J

Which of The following are classiFcatons describing how rock and oTher maTerial movedownslope?a. Fall, b. slide, c. slump, d. cr
nlexa [21]

Answer:

correct answer is Fall slide, slump, creep, flow

Explanation:

solution

we know that Movement of particle under the influence of gravity

so rock and other material move down as gravity.

first rock particle fall down because falls occur very rapidly with high slope after that they slide on the slope and after sliding they slump and it occurs when the rupture surface is curved after slump process they creep.  

after creeping, it can flow particle as it occurs slowly with the low slope with water.

so correct answer is Fall slide, slump, creep, flow

How is thermal equilibrium reached? Question 3 options: When both objects have the same temperature When objects have the same m
ollegr [7]

In the thermal equilibrium, the change in temperature is said to be zero in between the bodies. Thermal equilibrium is reached when both objects have the same temperature.

<h3>What is thermal equilibrium?</h3>

Thermal equilibrium is easily explained by the zeroth law of thermodynamics. If any two-body is at thermal equilibrium there is no change in the temperature of the body.

According to zeroth law if body A is in thermal equilibrium with body B and body B is in thermal equilibrium with C . So body A and C are also in thermal equilibrium.

In the thermal equilibrium, the net heat transfer is said to be zero in between the bodies.

Hence option A IS RIGHT. Thermal equilibrium is reached when both objects have the same temperature

To learn more about the thermal equilibrium refer to the link;
