work is distance * force so 15*100=1500
and to find time you know power = diastance * force / time
so 25=15*100/t
25=1500/t
25/1500=t
.016=time
The work done is 1500 Joules and the time required to do the work is 60 seconds.
The subject at hand is related to concepts in physics, specifically work and power.
To find the work done, we use the formula Work = Force x Distance. Substituting the given values:
Work = 100 Newtons x 15 meters = 1500 Joules
To find the time required to do the work, we use the formula Power = Work / Time. Substituting the given values and rearranging the formula to solve for Time gives us:
Time = Work / Power = 1500 Joules / 25 Watts = 60 Seconds

Answer:
The electromagnetic wave that travels the fastest through space is gamma ray
Explanation:
Electromagnetic wave is a type of wave which does not require material medium for its propagation. Examples of electromagnetic waves according to increasing frequency of the waves are gamma ray, x-ray, ultra violet ray, infra red, visible light, micro wave and radio waves.
Frequency of a wave is inversely proportional to period of oscillation of the wave. The higher the frequency of a wave, the shorter the period of oscillation. Gamma ray has the highest wave frequency in electromagnetic spectrum and shorter period of oscillation, thereby causing it to have the highest penetration power.
B) mechanical motion.
C) heat and light energy.
D) electrical and heat energy.
As per the question the crumpled paper was burnt .
When the paper was burnt,it produces light.One also feels the sensation of heat.
The electrical energy is due to the flow of electrons. Here no electronic motion takes place.Hence no electrical energy will be produced.
Mechanical energy is the sum total of kinetic and potential energy.The kinetic energy is the energy gained due to the motion of the body and potential energy is the energy gained due to the position or configuration of the body.
Hence from above,we can get that the correct answer to the question is-C] Heat and light energy.
Answer: The given statement is True.
Cells are the basic fundamental, structural, and functional unit of all living organisms.
Cells are the microscopic structures, which are responsible for performing all the functions of life. Thus, cells present in the body of living organisms can not be visible through naked eyes.
Therefore, the given statement is True.
Answer:
c = 13.5 m
Explanation:
from the attached diagram, we can apply the cosine rule to get the resultant displacement (c) where
c =
θ + β = 180 (sum of angles on a straight line )
θ + 55 = 180
θ = 180 - 55
θ = 125 degrees
c =
c =
c = 13.5 m
