The reflection of the candle in the concave mirror formed an upside-down real image that is smaller than the candle.
The characteristics of images formed in a mirrorThe mirror is an optic device that can either be plane or curved that produces an image through the law of reflection.
There are three main types of mirror which includes:
Plain mirrors,concave mirrors andconvex mirrors.The characteristics of the image formed by the concave mirror depends on the distance of the object from the mirror and it include the following:
It can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.Therefore, the reflection of the candle in the concave mirror formed an upside-down real image that is smaller than the candle.

26) An electron, moving toward the west, enters a uniform magnetic field. Because of this field the electron curves upward. The direction of the magnetic field is A) towards the north. B) towards the south. C) towards the west. D) upward. E) downward.
Answer: A
Explanation:
There is one important fact about magnetic fields. Magnetic fields are always perpendicular to the velocity of the particle, and the force acting on the particle. This is evident in the Lorentz force equation for magnetic fields, which states:
[tex]F=q(v x B)[/tex]
The cross product between between the velocity and the magentic field forms a force vector that is perpendicular to both the velocity and the field. In our example, the electron is traveling to the left, and the force it feels is upwards. One thing to keep in mind now, is that the Lorentz force equation is for positively charged particles. Therefore, whatever result we obtain for the field, it is actually the opposite since our particle is negatively charged.
Point your thumb in the direction of the velocity, and point your palm in the direction of the force. Your fingers should be pointing towards yourself (the south). This would be correct for positive charges, but it is the opposite for negative charges. The magnetic field points away from your body, which is the north.

why dull objects heat up faster than shiny objects......answer should not be from gooooggglee
Answer:
Shiny objects don't absorb heat as well as dull objects. Shiny objects reflect heat or they reflect more heat then absorb it. So the heat thats being hit on a shiny object is being reflected instead of being absorbed. Dull objects are better at aborbing heat. So that makes dull objects heat up faster than shiny objects, since shiny reflects more and dull doesn't as much.

In the first direct detection of gravitational waves by ligo in 2015, the waves came from.
In the first direct detection of gravitational waves by LIGO, the waves came from the merger of two black holes.
What is a Wave?
This is defined as propagation of disturbances from place to place in an organized manner.
In 2015, Laser Interferometer Gravitational-Wave Observatory(LIGO) observed gravitational waves which was a result of merger of two black holes and lasted fraction of a second.

If both masses are doubled, then the force
of gravity between them is quadrupled.
(True/False)
Answer:
True?
Explanation:Im sure of it?
According to the universal law of gravitation, the force between 2 objects (m1 and m2) is proportional to their plenty and reciprocally proportional to the sq. of the distance (R) between them.
Jack pulls a car up a hill. Jack does 405J of work on the car. If Jack walks 15m up the hill,
how large of a force must he exert.
Answer:
27N
Explanation: workdone = force * distance
Hence Force= workdone/distance
= 405/15
= 27N
Suppose that a spaceship is launched in the year 2120 on a round-trip journey to a star that is 100 light-years away, and it makes the entire trip at a speed of 99.99% of the speed of light. Approximately what year would it be on Earth when the ship returns to Earth
After completion of the trip described in the question, it would be the year 2320 on Earth.
Why would it be the year 2320?This has to do with the way light-years are described. A light-year is in fact not a measurement of time, but of distance. It is how far you would travel in one year if traveling at the speed of light. So since the star is 100 light-years away, it would take 100 Earth years to get there and then 100 more to get back, making the current Earth year 2320.
Therefore, we can confirm that after completion of the trip described in the question, it would be the year 2320 on Earth.
