Difference between universal law of gravitation and acceleration due to gravity​

Physics
1 answer:
marishachu [46]3 years ago
7 0

Explanation:

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.

G and g

In physics, G and g can be related mathematically as –

\(g=\frac{GM}{R^{2}}\)

Where,

1=g is the acceleration due to the gravity of any massive body measured in m/s2.

2=G is the universal gravitational constant measured in Nm2/kg2.

3=R is the radius of the massive body measured in km.

4=M is the mass of the massive body measured in Kg.

An "energy bar" contains 26 g of carbohydrates. For the steps and strategies involved in solving a similar problem, you may view
masha68 [24]

To solve this problem we will apply the definition of Power and Speed. In turn, we will consider that one gram of carbohydrate, according to numerous scientific studies, contributes around 17kJ of energy. Therefore, if this were true, the total energy of 26 grams would be

E = (26)(17000) = 4.42*10^5J

Power can be described as the amount of energy applied at a given time, that is,

P = \frac{E}{t} \rightarrow t = \frac{E}{P}

t = \frac{4.42*10^5}{380}

t = 1.16*10^3s

The speed is described as the distance traveled in a certain time, and its units in international system is m / s, converting and replacing we will have

v = 5km/h(\frac{1000m}{1km})(\frac{1h}{3600s})

v = 1.388m/s

Now,

v = \frac{d}{t} \rightarrow d = vt

The distance is,

d = vt

d = (1.388)(1.16*10^3)

d = 1610.08m

Therefore the distance walked is 1610.08m

Paul and Ivan are riding a tandem bike together. They’re moving at a speed of 5 meters/second. Paul and Ivan each have a mass of
VMariaS [17]
<span>If Paul and Ivan has a speed of 5 meters/second in which their combined mass is 50 kg. To increase the bike's kinetic energy, Paul must increase its speed as well. Increasing his speed allows an increase in momentum of them running the bike. The kinetic energy equation is KE = 0.5mv</span>² where m is mass, v is speed and KE is kinetic energy.

Consider the following three objects, each of the same mass and radius: (1) a solid sphere (2) a solid disk (3) a hoop All three
Vinil7 [7]

Answer:

The correct answer is

a) 1, 2, 3

Explanation:

In rolling down an inclined plane, the potential energy is Transferred to both linear and rotational kinetic energy thus

PE = KE or mgh = 1/2×m×v² + 1/2×I×ω²

The transformation equation fom potential to kinetic energy is =

m×g×h = \frac{1}{2} mv^{2} + \frac{1}{2} (\frac{2}{5} mr^{2} )(\frac{v}{r}) ^{2}

v_{Sphere} = \sqrt{\frac{10}{7} gh}

v_{Hoop} = \sqrt{gh}

v_{Disc}=\sqrt{\frac{4}{3} gh}

Therefore the order is with increasing rotational kinetic energy hence

the first is the sphere 1 followed by the disc 2 then the hoop 3

the correct order is a, 1, 2, 3

An ice skater spins at 2.5 rev/s when his arms are extended. He draws his arms in and spins at 10.0 rev/s. By what factor does h
Rainbow [258]

Answer:

The moment of inertia decreased by a factor of 4

Explanation:

Given;

initial angular velocity of the ice skater, ω₁ = 2.5 rev/s

final angular velocity of the  ice skater, ω₂ = 10.0 rev/s

During this process we assume that angular momentum is conserved;

I₁ω₁ = I₂ω₂

Where;

I₁ is the initial moment of inertia

I₂ is the final moment of inertia

I_2 = \frac{I_1 \omega_1}{\omega_2} = \frac{I_1*2.5}{10} \\\\I_2 = 0.25I_1 = \frac{1}{4}I_1

Therefore, the moment of inertia decreased by a factor of 4
