PHYSICS QUESTION!!!!

geniusboy [140]

<u>Answer:</u>

A) Mass of dinosaur = 77,000 kg

Weight of dinosaur = 755370 N

B) Mass of dinosaur = 77,000 kg

Weight of dinosaur = 377685 N

<u>Explanation:</u>

A) Mass of dinosaur the brachiosaurus = 77,000 kg

We have weight of body = mg = 77,000*9.81 = 755370 N

B) Mass of a body is constant, it will not get affected by change in acceleration due to gravity value.

So, Mass of dinosaur = 77,000 kg

We have weight of body = mg' = m*g/2 = 77,000*9.81/2 = 377685 N

If the distance between two masses is tripled, the gravitational force between changes by a factor of:_______

adell [148]

Answer:

option A

Explanation:

given,

distance between two masses is doubled

new distance, r' = 3 r

using gravitational force equation

$F = \dfrac{GMm}{r^2}$ ............(1)

new gravitational force

$F' = \dfrac{GMm}{r'^2}$

now from the given condition

$F' = \dfrac{GMm}{(3r)^2}$

$F' = \dfrac{GMm}{9r^2}$

$F' = \dfrac{1}{9}\dfrac{GMm}{r^2}$

now, from equation (1)

$F' = \dfrac{1}{9}F$

$\dfrac{F'}{F} = \dfrac{1}{9}$

now, the change in gravitational force factor is equal to $\dfrac{1}{9}$

Hence, the correct answer is option A

Examples of uniform velocity

slava [35]

Explanation:

When a truck travels in equal distances in equal intervals of time then we say that the body has got a uniform velocity. In the above example a truck is traveling at 5 miles in all the positions at A, B, and C and all in the intervals of 5 minutes each.
