The answer is Film Badge
Answer:
False
Explanation:
Answer:
11.11 s
Explanation:
Given:
u = 80 km/h = 22.22 m/s
v = 160 km/h = 44.44 m/s
a = 2.0 m/s²
Find: t
v = u + at
44.44 m/s = 22.22 m/s + (2.0 m/s²) t
t = 11.11 s
b. violence and intimidation
c. passive resistance
d. running for political office
Water is placed at room temperature at 20 degree C
now after some water evaporate at room temperature
so here we can say speed of water molecules will not change as the temperature is same after evaporation
as we know that total kinetic energy is given by
since temperature is same then energy will not change here
now as water evaporate to vapors then we can say that here all molecules are separated more in vapor phase so force of interaction will be less in this phase
And since potential energy depends on the force so potential energy will decrease in this phase
A. Gases missing with particles
B. liquid moving through a vacuum
C. moving Particles
D. Electromagnetic waves
The correct answer to the question is D. Electromagnetic waves.
EXPLANATION:
As per the diagram, the radiations are emitted by sun is coming to earth.
The radiations coming from sun is electromagnetic in nature. It does not require any medium for its propagation. It travels a long distance in vacuum or space to reach earth.
It contains both electric field and magnetic field which are perpendicular to each other and also normal to the direction of propagation. The diagram shows that the wave is moving in the form of crests and troughs.
If we consider the wave nature of radiation, then it is one way of transportation of thermal energy from sun to earth which is known as radiation.
Hence, the arrows drawn in the figure is electromagnetic waves.
