Explanation:
the temperature will determine the kinetic energy or degree of freedom of the molecules of matter.
if the temperature is high, the kinetic energy of the molecules increase which may cause a change of state into a gas which has molecules of high kinetic energy. this shows that temperature is a measure of the kinetic energy of the molecules.
how long do a Tortoise live in the earth?
Answer:
80 to 150 years
Explanation:
hope I helped
Answer: 80-150 years and some over 150 years
Explanation:
There are different types of Tortoise in earth everyone eith different lifespan. So basically normal ones have 80-150 while some other like giant tortoise even have over 150 years.

A baseball pitcher throws a 0.14 kg ball toward a batter who is 18 m away.
The ball is traveling at 40 m/s when it leaves the pitcher's hand. What is the
ball's kinetic energy at this point?
A. 112 J
OB. 224 J
C. 12J
D. 3 J
SUBMIT
Answer:
A. 112 J
Explanation:
KE = ½mv² = ½(0.14)40² = 112 J
how much force is needed to stop a body of mass 10kg
Answer:
Force of 100 N will be needed.
Explanation:
[tex]Force, F = m \times g[/tex]
g is acceleration due to gravity
m is the mass
[tex] F = (10 \times 10) \\ F = 100 \: newtons[/tex]
Answer:
The answer is
Explanation:
A force of atleast a 100 N would be needed.....

How does mercury differ from other metals?(1 point)
It does not conduct electricity.
It is not lustrous.
It is not solid under normal conditions.
It does not chemically react with other elements.
Answer:
It is not solid under normal conditions
Mercury differs from other metals as It is not solid under normal conditions. It is the only metal that is liquid at room temperature, therefore the correct answer is option C
What is the matter?Anything which has mass and occupies spaces is known as matter, mainly there are four states of matter solid liquid gases, and plasma.
These different states of matter have different characteristics according to which they vary their volume and shape.
Because it is not solid under normal circumstances, mercury is different from other metals. Because it is the only metal that is liquid at room temperature,
Thus the correct answer is option C

define radiation explain it
Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

What the suns mass in scientific notation????
Explanation:
In scientific notation the Sun's mass is: =1.989 x 10 ^30 kg
Answer:
I think in scientific notation the Sun's mass becomes: M Sun = 1.989 x 10 30 kg. The number above the ten, called the power of ten or exponent, stands for the number of decimal places. If it is positive, as in the mass of the Sun, the decimal places are in front of the decimal point.
I hope this help you!:)

if vector A=2i+3j-k and vector B=4i+6j-2k. The angle between them will be: a) 0°b)45°c)90°d)60°
Notice that
B = 4i + 6j - 2k = 2 (2i + 3j - k) = 2A
so both vectors point in the same direction and the angle between them is (A) 0°.

A 210 Ohm resistor uses 9.28 W of
power. How much current flows
through the resistor?
(Unit = A)
Current=I
[tex]\boxed{\sf P=I^2R}[/tex]
[tex]\\ \sf\longmapsto I^2=\dfrac{P}{R}[/tex]
[tex]\\ \sf\longmapsto I^2=\dfrac{9.28}{210}[/tex]
[tex]\\ \sf\longmapsto I^2\approx0.04[/tex]
[tex]\\ \sf\longmapsto I\approx\sqrt{0.04}[/tex]
[tex]\\ \sf\longmapsto I\approx\sqrt{\dfrac{4}{100}}[/tex]
[tex]\\ \sf\longmapsto I\approx\dfrac{\sqrt{4}}{\sqrt{100}}[/tex]
[tex]\\ \sf\longmapsto I\approx\dfrac{2}{10}[/tex]
[tex]\\ \sf\longmapsto I\approx0.2A[/tex]

The fluid inside the hydraulic jack has a pressure of 30,000 Pa. If the surface of
the piston that is used to lift an object is 0.1 m’in area, how much weight can
the jack lift?
Explanation:
p = F /A
F = P×A
F = 30,000 Pa / 0.1 m²
F = 300,000 N
There is no centripetal force if the object moves in a long line. True or False?
Answer:
true
Explanation:
i think it's true because according to newtons first law of motion an object continues in motion unless compelled by an external force, this external force is known as the centripetal force.
