Physics
1 answer:
vodka [1.7K]3 years ago
6 0

Answer:

Gravitone

Explanation:

In theories of quantum gravity, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravity. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity.

Georgia is jogging with a velocity of 4 m/s when she accelerates at 2 m/s2 for 3 seconds. How fast is Georgia running now?
professor190 [17]
Georgia is moving by uniformly accelerated motion, with initial velocity 
v_0 =4 m/s
and with constant acceleration  of
a=2 m/s^2
so her velocity at time t is given by
v(t) = v_0 + at = 4 m/s + (2 m/s^2)(3 s)= 10 m/s
So now Georgia is running at 10 m/s.

Which of the outer planets is MOST like Earth? How?
Over [174]

Answer:

It is not impossible to answer the question, my apologies for “discrediting” the answer it would have to be Venus, the outer planet most similar to earth.

Explanation:

Venus is very similar to earth, as many studies, research, factual intellectual based concepts - the size, shape, surface gravity, average density, mass, average days of 24 hours, season changes similar to earth, and tilted axis. As well as similar climate make Venus the most accurate answer.

Hope this helps! Thank you for your time.

4. How many neutrons are there in an atom of protium? Deuterium? Tritium? <br> P
insens350 [35]
The main difference between protium, deuterium, and tritium is that protium has no neutrons in its nuclei, whereas deuterium is composed of one neutron and tritium is composed of two neutrons [17]. Protium is an isotope of hydrogen that is composed of one proton and one electron.

Two forces, 80N and 100N acting at an angle of 60 degrees with each other, pull on an object. What single force would replace th
KIM [24]

We use the law of Cosines, resultant force

F =\sqrt{(F_{1})^2 + (F_{2})^2 + 2 F_{1} F_{2} cos  \theta   }

Here, (F_{1}) and (F_{2}) are forces acting at angle \theta with each other.

Given F_{1} = 80 N, F_{2} = 100 N and \theta = 60^0.

Substituting these given values in above formula we get

F =\sqrt{(80)^2 + (100)^2 + 2 \times 80 \times 100 \ cos 60^0     } = 156. 20 \ N.

Thus, the resultant force is 156 N.
