Answer:

his is an example of the transformation of gravitational potential energy into kinetic energy

Explanation:

The game of juggling bowling is a clear example of the conservation of mechanical energy,

when the bolus is in the upper part of the path mechanical energy is potential energy; As this energy descends, it becomes kinetic energy where the lowest part of the trajectory, just before touching the hand, is totally kinetic.

At the moment of touching the hand, a relationship is applied that reverses the value of the speed, that is, now it is ascending and the cycle repeats.

Therefore this is an example of the transformation of gravitational potential energy into kinetic energy

A 2.5-L tank initially is empty, and we want to fill it with 10 g of ammonia. The ammonia comes from a line with saturated vapor

Alex17521 [72]

Answer:

592.92 x 10³ Pa

Explanation:

Mole of ammonia required = 10 g / 17 =0 .588 moles

We shall have to find pressure of .588 moles of ammonia at 30 degree having volume of 2.5 x 10⁻³ m³. We can calculate it as follows .

From the relation

PV = nRT

P x 2.5 x 10⁻³ = .588 x 8.32 x ( 273 + 30 )

P = 592.92 x 10³ Pa

Calculate the wavelength of a neutron that has a velocity of 200. cm/s. (the mass of a neutron = 1.675 × 10–27 kg and h = 6.63 ×

Licemer1 [7]

To find the wavelength of a neutron can be calculated by using the formula Wavelength=h/m x v Where h is planck's constant m=mass of neutron v= velocity of the particle By substituting the given values Wavelength= 6.63 × 10–34 j s / 1.675 × 10–27 kg x 2 m/s^-1 Wavelength of a neutron=1.979 x 10^-7 m

Car B is following Car A and has a greater speed than Car A. the two cars are moving in a straight line and in the same directio

ElenaW [278]

Answer:

Collision force will be same in both the cases.

Explanation:

A perfectly inelastic collision is said to take place when a system loses the amount of its Kinetic Energy at its maximum. In a perfectly inelastic collision, the colliding particles stick to each other. In such a collision, kinetic energy is lost by combining the two bodies with each other.

In situation 1:

Speed of Car A, $v_{A} = 10 mph$

Speed of Car B, $v_{B} = 20 mph$

Relative speed of car A and car B, $v = v_{b} - v_{a} = 10 m/s$

Now, in the situation 2:

Speed of car A, $v_{A} = 30 mph$

Speed of car B, $v_{B} = 40 mph$

Relative speed of car A and car B, $v = v_{b} - v_{a} = 10 m/s$

Therefore, Car A and Car B both have the same relative speed, v = 10 m/s

Explain some of the environmental advantages and disadvantages of upward urban growth.

Lena [83]

Disadvantage: Living outside the city makes having a car almost a requirement. Businesses, schools, services, and recreational areas are all spread out at a distance, not to mention the need to commute to work.

Advantage: The cost of a house with a yard in the suburbs is often less than the cost of a condominium or quality apartment in the city.

The heating coils in you toaster during the first five seconds after you turn the toaster on is Δ K = W + Q.

Your automobile just before you fill it with gas until you pull away from the gas station at speed v is ΔK + ΔU + ΔEint = W + Q + TMW + TMT

your body while you sit quietly and eat a peanut butter and jelly sandwich for lunch is ΔEint = Q + TET + TER
