If it takes 726 watts of power to move an object 36 m in 14 s, what is the mass of the object?
Answers
Answer:
Explanation:
Given
Power (p)= 726 watt
Time (t) = 14 sec
distance travelled (d; h) = 36 m
mass (m) = ?
we know
Power (p) = W/t ( w = work done )
p = m * g * h / t ( w = m * g* h)
726 = m * 10 * 36 / 14 ( g = 10 m/s^2)
m = 28. 23 kg
or if we use the value of g as 9.8 m/s^2
the mass will be
= 28.8 kg
hope it helps :)
The mass of the object if it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.
What is mass?An object's inertia, a fundamental property, is measured by its mass, a fundamental indicator of the volume of substance inside the thing. Definitions of mass can seem circular since it is such a fundamental quantity and is challenging to define in terms of another.
It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.
Given:
The Power, p = 726 watt
The Time, t = 14 sec
distance travelled, d = 36 m
Calculate the power by the given formula
p = W / t
p = m * g * h / t ( w = m * g* h)
726 = m * 9.8 * 36 / 14 ( g = 10 m/s^2)
m = 28. 8 kg
Therefore, the mass of the object If it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.

Testing shows that a sample of wood from an artifact contains 12.5% of the original amount of carbon-14. Given that the half-life of carbon-14 is 5730 years, how old is the artifact?
A. 22,920 years
B. 17,190 years
C. 11,460 years
D. 5730 years
Answers
Answer:
B. 17,190
Explanation:
got it right, trust
The age of the artifact is 17190 years. So, the correct option is B.
What is meant by half life ?The amount of time needed for half of a radioactive sample's atomic nuclei to spontaneously decay (transform into another nuclear species by producing particles and energy) is known as the half-life.
Here,
Amount of Carbon-14 present in the given sample = 12.5 %
Given that the half-life of Carbon-14 is 5730 years. That means after a period of 5730 years, the percentage of Carbon-14 present in the sample will be 50% of the original amount.
So, age of the artifact when 50% is present is 5730 years.
Thus, after a period of 2 half-lives, the amount of carbon-14 present will be, 25%.
So, age of the artifact when 25% is present,
t = 2 x 5730 = 11460 years
Therefore, we can say that,
The age of the artifact when 12.5% is present,
t' = 3 x 5730 = 17190 years
Hence,
The age of the artifact is 17190 years. So, the correct option is B.

B. The average molecular speed in the high-temperature gas is faster than the average molecular speed in the low-
temperature gas.
C. Both A and B are true.
D. Neither A nor B is true.

I think it is C
Explanation:
If the temperature of a gas increases, the gas particles have a higher average speed as they gain kinetic energy. They collide more frequently with the walls of the container, which produces a bigger pressure.
What is the temperature increase of 4.0 kg of water when it is heated by an 8.0 ^102 W immersion heater for exactly 10.0 min? (cp = 4186 J/kg·°C)
Answers
Answer:
ΔT = 28.667°C is the answer.
Explanation:
Given,
Mass of water = 4.0 kg
Water is heated by = 8 × 10² W = 800 W
Time = 10 min = 10 × 60 = 600 s
Now,
using the equation of specific heat,
Q = mcΔT
where c is the specific heat capacity of water = 4186 J/kg°C
Q = Pt
Substituting,
Pt = mcΔT
800 × 600 = 4 × 4186 × ΔT
480000 = 16744 × ΔT
ΔT = 28.667
∴Temperature increased, ΔT = 28.667°C

Minute after minute, hour after hour, day after day, ocean waves continue to splash onto the shore. Explain why the beach is not completely submerged and why the middle of the ocean has not yet been depleted of its water supply. A) Ocean waves can only bring water to the shore but cannot take it back. The momentum of the water particles switches direction when the wave hits the shore and this momentum takes all the water back into the ocean. B) Ocean waves bring the water and also take it all the way back into the ocean. As such, water does not pile up on the beach. C) Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position. D) None of the choices are correct.
Answers
Answer: C. Ocean waves can only bring energy to the shore; the particles of the medium (water) simply oscillate about their fixed position.
Explanation:
The reason why the beach is not completely submerged and the reason why the middle of the ocean has not been depleted of its water supply is due to the fact that water isn't transported by ocean waves.
It should be noted that even a single drop of water cannot be brought by the ocean wave to the shore from the middle of the ocean.
The only thing that the ocean waves can bring to the shore is energy. Hemce, the water particles oscillate in their fixed position which is vital in making sure that the beach isn't piled up with water.
