Answer:
The correct answer is d Both the observer's are correct
Explanation:
We know by postulates of relativity that laws of physics are same in different inertial frames.
Thus for each of the frames they make observations related to their frames and since the observations are true for their individual frames they both are correct. But when we compare the two frames we need to use transformation equations to compare both the results.
Answer:
Look at work
Explanation:
Elastic Collision: Ki=Kf
M1=4.65kg
M2: 0.060kg
v1=5m/s
v2=0m/s
4.65*5+0.060*0=4.65*v1'+0.060*v2'
23.25+0=4.65v1'+0.060v2'
Also since it is an elastic collision we can use
v1+v1'=v2+v2'
4.65+v1'=v2'
4.65+v1'=v2'
Substitute into the earlier equation
23.25=4.65v1'+0.060(4.65+v1')
Expand
23.25=4.65v1'+0.279+0.06v1'
Solve for v1'
22.971=4.71v1'
v1'=4.88m/s
v2'=4.65+4.88=9.53m/s
The mass of the proton is:
and the mass of the antiproton is exactly the same, so the total mass of the two particles is
.
In the annihilation, all the mass of the two particles is converted into energy, and the amount of this energy is given by Einstein's equivalence between mass and energy:
where M is the mass converted into energy and c is the speed of light. In this example,
, therefore the energy released is
The weight of 100 kg mass on Saturn is 10,192 N.
The weight of 7.0 kg mass on Pluto is 2.01 N.
The given parameters;
- <em>acceleration due to gravity, = 10.4g</em>
- <em>mass of the Saturn, m = 100 kg</em>
- <em>acceleration due to gravity on mercury, = 3.59 m/s²</em>
The weight of 100 kg mass on Saturn is calculated as follows;
W = mg
W = 100 x 10.4 x 9.8
W = 10,192 N
The weight of 7.0 kg mass on Pluto is calculated as follows;
W = 7 x 0.08 x 3.59
W = 2.01 N

Answer:
C. Heat
Explanation:
HEAT is energy that is transferred due to a difference in temperatures.
