Answer:

Thermal energy

Explanation:

Thermal energy refers to the energy due to the random motion of the particles inside a substance/objects. The faster the particles moves in an object, the more thermal energy it can transfer. This is also directly related to the concept of temperature of an object: the higher the temperature of an object, the faster its particles move, the more thermal energy the object can transfer.

According to the basic laws of thermodynamics, thermal energy (also called heat) is always transferred spontaneously from an object at higher temperature to an object at lower temperature. In this problem, the hot mug is warmer than Javier's hand, so thermal energy is transferred from the hot mug to Javier's hand.

A uniform bridge 20.0 m long and weighing 400000 N is supported by two pillars located 3.00 m from each end. If a 19600 N car is
Svetradugi [14.3K]

Answer:

P = 238475 N

Q = 181125

Explanation:

From the diagram attached below,

For the bridge to be at equilibrium,

Sum of upward force = sum of downward force

P+Q = 400000+19600

P+Q = 419600.................. Equation 1

Taking  moment about support A

sum of clockwise moment = sum of anti clockwise moment.

400000(10-3)+19600(8-3) = Q(20-6)

2800000+98000 = 16Q

2898000 = 16Q

Q = 2898000/16

Q = 181125 N.

Substitute the value of Q into equation 1

P+181125 = 419600

P = 419600-181125

P = 238475 N.

Hence, support A exert a force of 238475 N and support B exert a force of 181125 N

According to the big-bang theory how the universe might end?
Troyanec [42]

Answer:

<em>If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.</em>

6. A lumberjack is standing on a log floating on a lake. She starts from rest, then runs along the log to the end, when she jump
scoray [572]

Answer:

a) -3.267 m/s

b) 2.227 m/s

Explanation:

As per the conservation of momentum

m1v1 + m2v2=0

m1= mass of log

m2 = mass of lumber jack

v1 = velocity of log

v2 = velocity of lumber jack

a) Velocity of first log

-\frac{70*7}{150} = -3.267 m/s

b) m1v1 + m2v2 = m3v3

Velocity of log

= \frac{70*7}{150+70} \\2.227

Consider two spaceships, each traveling at 0.50c in a straight line. Ship A is moving directly away from the Sun and ship B is a
attashe74 [19]

Answer:

The velocity of the light will be 1.0c only

Explanation:

The velocity of the light measured in the case given in question will be 1.0c only.

This is due to the fact that the velocity of light is never relative. The velocity of the light is maximum

The velocity of the light cannot be scaled down in no case

Thus, the velocity of the light remains as constant.

Hence, the velocity of the light measured will be 1.0c although the ships have relative velocity.
