MARKING BRAINLIST | Which situation below would have the STRONGEST gravitational force between them?

maks197457 [2]

Case d) has the strongest gravitational force

Explanation:

The magnitude of the gravitational force between two objects is given by the equation:

$F=G\frac{m_1 m_2}{r^2}$

where :

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between the objects

a) For this pair of objects:

m1 = 10 kg

m2 = 2 kg

r = 30 km = 30,000 m

So the gravitational force is

$F=(6.67\cdot 10^{-11})\frac{(10)(2)}{30000^2}=1.48\cdot 10^{-18}N$

b) For this pair of objects:

m1 = 10 kg

m2 = 10 kg

r = 30 km = 30,000 m

So the gravitational force is

$F=(6.67\cdot 10^{-11})\frac{(10)(10)}{30000^2}=7.41\cdot 10^{-18}N$

c) For this pair of objects:

m1 = 2 kg

m2 = 2 kg

r = 10 km = 10,000 m

So the gravitational force is

$F=(6.67\cdot 10^{-11})\frac{(2)(2)}{10000^2}=1.33\cdot 10^{-17}N$

d) For this pair of objects:

m1 = 10 kg

m2 = 10 kg

r = 10 km = 10,000 m

So the gravitational force is

$F=(6.67\cdot 10^{-11})\frac{(10)(10)}{10000^2}=6.67\cdot 10^{-17}N$

Therefore, the strongest gravitational force is in case d).

F a forklift raises a 76-kg load a distance of 2.5 m, about how much work has it done?

sleet_krkn [62]

W= FxD. Since the weight is not put into force you’re going to convert it by multiplying it by 9.8 (gravity). 76kg x 9.8 = 7448. Then multiply that by the distance (2.5). Your answer is 1862.

A 0.140 m high cylinder

solmaris [256]

Answer:

The value of pressure inside the cylinder is 18.68 K Pa.

Explanation:

Given data

Height h = 0.14 m

Density $\rho$ = 13600 $\frac{kg}{m^{3} }$

We know that

Pressure inside the cylinder is given by the formula

P = $\rho$ g h ------- (1)

here

$\rho$ = density of fluid = 13600 $\frac{kg}{m^{3} }$

g = acceleration due to gravity = 9.81 $\frac{m}{s^{2} }$

h = height of the cylinder = 0.14 m

Put all the values in above equation

P = 13600 × 9.81 × 0.14

P = 18678.24 Pa

P = 18.68 K Pa

Therefore the value of pressure inside the cylinder is 18.68 K Pa

What formula do I use for the second question? For number 3 how is one energy converted to the other? ( using arrows ) I get num

Fed [463]

#2
Use the formula ... Kinetic energy = (1/2) x (mass) x (speed)²

#3 - a).
sun => energy travels as electromagnetic waves => reaches Earth as
 heat & light energy.

sun => absorbed in plants => eaten by animals => animals die =>
 decay into oil in millions of years => we burn the oil to get the energy.

#3 - b).
food I ate for lunch => metabolized into glucose by my body
 => some of it burned in my muscles to generate energy for immediate needs
 => the rest of it stored as fat for future needs.

#3 - c).
flower pot rolls off the ledge => gravity does work on it all the way down,
 producing the kinetic energy it has when it hits the floor.

#3 - d).
oil or natural gas is burned, releasing heat energy => energy is used
 to generate electricity => electricity flows through cables from the
 power generating plant to your home => hot plate plugged into the
 wall => turns electrical energy back into heat energy => heat energy
 is conducted into the bottom of the beaker, flows through the glass
 to the inside surface => heat energy is conducted from the inside of
 the glass to the water, which gets hotter as it absorbs more energy.
=============================

Note:
#1 on the sheet is wrong.
"Work = force x distance" that's correct
But 25-kg is the mass of the ball, not the gravitational force on it.
The force on it is (mass) x (gravity), called its "weight".
 That's (25-kg) x (9.8 m/s²) = 245 kg-m/s² = 245 newtons .
