So what is 27+22? Is it
A 8338
B 8282
C 8228
D 8234
Answer:
You put the add sign, so it would be 49. I don't believe that is what you meant to put though.
Explanation:
i gotchu, 27+22 so you take the 8 and multiply that by the number of times you blink every 2 minutes and then divide that by 0×1 and carry the 3 and that gives you -7
Water is a great conductor of electricity. True or False
Answer:
False
Explanation:
Think about every warning on electrical products, which is 'DO NOT KEEP NEAR WATER'
Answer:
FALSE
Explanation:
Pure water is not a good conductor of electricity. ... Because electrical current is carried by ions in solution, conductivity increases as the ion concentration increases. In such a way, that the conductivity when water dissolves ionic compounds.

Un cuerpo cuya masa es de 20 kg se lleva primero a la luna y luego a marte. Teniendo en cuenta el factor que liga masa y peso en marte es de 3,8 N/Kg
Answer:
W = 76 N
Explanation:
In this exercise you are asked to find the weight of the body.
Mass is a quantity that is invariant, it measures the same everywhere, the weight depends on where it is measured, a simple way to find the weight of a body is
W = g m
where g is the constant of the place, in this case we have the weight of the body on Mars and its mass which is constant on Earth and on Mars
W = 3.8 20
W = 76 N
Planetesmals are made from
A planetesimal is an object formed from dust, rock, and other materials. According to the planetesimal hypothesis, when a planetary system is forming, there is a protoplanetary disk with materials from the nebulae from which the system came. This material is gradually pulled together by gravity to form small chunks.

5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,
Explanation:
4) This exercise is asked to give some examples of thermal and electrical energy transfer
the transfer of thermal energy occurs when we grasp a hot or cold body due to the difference in temperature between the body and us there is an exchange of heat, for example when drinking a cup of hot coffee there is a transfer of energy from the cup to the hand .
If we take a can of cold soda there is a transfer from hand to can.
Electrical transfer occurs, for example, when a current passes through a light bulb, it becomes incandescent and gives light.
In all modern electrical appliances there is transformation of electrical energy
5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,
For example, when you lift a box, the potential energy of the box increases with height, but the energy of the person decreases because it does work that is negative.
In amusement park rides, the energy accumulated in one part of the game generally with height is transformed into energy of movement in another part of the game, but the total energy remains constant.

Heating up a reaction speeds up the rate of the reaction because...
A. The particles collide more and have more energy
B. The particles collide less
C. The particles collide less and have less energy
D. The particles collide more with the correct orientation
Answer:
A.
Explanation:
more heat = heat energy becomes more kinetic energy = more particle collision
Answer:
the answer is A.There is increased kinetic energy making them collide more and speeds up the rate of reaction.

Types Of Energy Transfers
Heat can be transferred in three ways: by conduction, convection, and by radiation.
Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer of heat by electromagnetic waves.Can you please help me?

A constant speed is __________ because the distance traveled per unit of the time does not remain the same
Answer:
velocity
Explanation:
velocity is really speed with direction but is what remains constant as the distance changes.
Convertir 1200 ms a cs
Convertir 0,3 mm a cm.
Answer:
You can do the reverse unit conversion from cm/s to m/s, or enter any two units below: Metre per second (U.S. spelling: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.

What variable do you think made this airplane fly the farthest?
Answer:
How does the weight of the nose on a paper
airplane affect the distance it will travel
when measured in centimeters?
EXPERIMENT CONCLUSION: (Explain whether or
not your data supports, or fails to support your identified
prediction. Explain why, including facts and details!)
The distance did increase when I added 1 paper clip.
However, I was surprised that the distance decreased
when I added a second paper clip. I believe this
happened because the nose of the plane became too
heavy. When the plane was released, the nose of the
plane descended much quicker. I think the plane was
more balanced in weight when only 1 clip was on the
nose.
A meteor moving through space speeds up as it gets closer to Earth. What force causes the meteor's speed to increase the closer it gets to Earth?
PLS Help
Answer:
gravity
Explanation:
its hard to explain its one of the resons we do gravity assists for space probes and such the meteor will catch earths gravity and be pulled in by it if you look at sednas orbit as it gets closer to the sun it speeds up.
The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.
What is meant by gravity ?Gravity is defined as the force by which a planet attracts another body towards its center.
Here,
The meteor was moving through space and the speed of the meteor started increasing as it moves closer to the earth.
This is because of the gravitational force of earth that is being exerted on the meteor. Gravitational force of earth is defined as the force of attraction that the earth exerts on another body in its gravitational field and draws them towards the center of the earth.
As the meteor moves towards the earth's , it gets accelerated by the earth's gravitational field such that the speed of the meteor increases and thus it attains more kinetic energy. As a result, the meteor moves faster when it gets closer to earth. This is because of the force of gravity of the earth.
Hence,
The force that causes the meteor's speed to increase as it gets closer to Earth is the gravitational force of earth.

Convert the temperature of the air in a room air-conditioned to 20.0 degrees Celsius to equivalent temperatures on the Fahrenheit and Kelvin scales.
Answer:
Freezing Water Boiling Water
Centigrade 0 100
Fahrenheit 32 212
Kelvin 273 373
One needs to know these values for an understanding of the temperature scale
9/5 C + 32 = F Check for boiling points
5/9 (F - 32) = C
Example:
F = 9/5 C + 32 = 9/5 * 20 + 32 = 68 F
And deg K = C + 273
So 20 deg C = 293 deg K
Answer:
68 F and 293.16 K
Explanation:
T F= 1.8(20) + 32 = 68 F
TK= 20 +273.16 = 293.16 K
