Explanation:

In this case, we need to write correct statement about the topics :

1. Kepler's first law of planetary motion = the orbit of each planet about the Sun is an ellipse with the Sun at one focus.

2. Newton's third law of motion = for any force, there is an equal and opposite reaction force.

3. Kepler's second law of planetary motion = a planet moves faster in the part of its orbit nearer the Sun and slower when farther from the Sun, sweeping out equal areas in equal times.

4. Newton's second law of motion = force = mass x acceleration

5. Kepler's third law = more distant planets orbit the Sun at slower average speeds obeying the mathematical relation, p^2=a^3

6. Newton's second law of motion = an object moves at constant velocity if there is no net force acting upon it

Hurricanes are especially destructive because of the abrupt decrease in air pressure that they bring with the winds. Consider a
ivann1987 [24]

Answer:

2.96 × 10^4 N

Explanation:

1 atm = 101325 N/m², pressure inside the airtight room = 1.02 atm, pressure outside due to hurricane = 0.91 atm

net pressure directed outward = P inside - P  outside

net pressure = 1.02 - 0.91 = 0.11 atm

where 1 atm = 101325N/m²

0.11 atm = 0.11 × 101325 N/m² = 11145.75 N/m²

area of the square wall = l × l where l is the length of the wall in meters = 1.63 × 1.63 = 2.6569

net pressure = net force / area

make net force subject of the formula

net force = net pressure × area = 11145.75 × 2.6569 = 2.96 × 10 ^4 N

you add equal amounts of heat to two identical cylinders containing equal amounts of the same ideal gas. cylinder a is allowed t
OleMash [197]

Temperature rise will be there in cylinder B more than in cylinder A because of internal energy.

what is internal energy?

The sum of the kinetic and chemical potential energies of all the particles in the system is the internal energy. Particles accelerate and pick up kinetic energy when energy is applied to increase the temperature.

Briefing:

Cylinder A uses the heat it absorbs to both work while expanding and to increase internal energy (or temperature).

While cylinder B solely uses the heat it absorbs to increase its internal energy 

As a result, cylinder B's temperature rise is greater than cylinder A's.

During a workout, the football players at State U ran up the stadium stairs in 61 s. The stairs are 130 m long and inclined at a
NeTakaya

Answer:

  P = 1097 Watt

Explanation:

given,

length of stairs, L = 130 m

inclination with horizontal,θ = 30°

mass of the football player = 105 Kg

time = 61 s

we know,

Power = \dfrac{work}{time}

Work = change in Potential energy

 h = L sin 30°

 h = 130 x 0.5

 h = 65 m

W = m g h

W = 105 x 9.8 x 65

W = 66885 J

now,

P = \dfrac{66885}{61}

  P = 1097 Watt

hence, the power output on the way is 1097 W

A 2.00-kg rock has a horizontal velocity of magnitude 12.0 m>s when it is at point P in Fig. E10.35. (a) At this instant, wha
zaharov [31]

Answer:

(A) L = 115.3kgm²/s

(B) dL/dt = 94.1kgm²/s²

Explanation:

The magnitude of the angular momentum of the rock is given by the foemula

L = mvrSinθ

We have been given θ = 36.9°, m = 2.0kg, v = 12.0m/s and r = 8.0m.

Therefore L = 2.00 × 12 × 8.0 × Sin 36.9° =

115.3 kgm²/s

(B) The magnitude of the rate of angular change in momentum is given by

dL /dt = d(mvrSinθ)/dt = mgrSinθ = 2.00 × 9.8 × 8.0× Sin36.9 = 94.1kgm²/s²
