Answer:
Unit of energy is kg-m/s or Joules.
Explanation:
The mass- energy relationship in physics is given by :
Where
m is the mass of the object
c is the speed of light
The SI unit of m is kilogram while the SI unit of c is as same as speed of light i.e. m/s. So, the unit of energy is kg-m/s. It is also equivalent to Joules.
So, the SI unit of energy is kg-m/s or Joules. Hence, this is the required solution.
Answer: you'll see cyan color on the screen
Explanation:
Saturating the red cone causes them to stop functioning, hence you can't perceive the red part of white light. White light is made up of three main colors which are blue, red and green. When one can no longer perceive the red part of light, one is left with the grean and blue part. The green and blue part of light will superimpose to give a cyan color.
Answer:
The answer to your question is 6 km/s
Explanation:
Acceleration is a change in velocity with respect to time, its units are m/s² or km/h².
Data
vo = 15 km/h
vf = 45 km/h
t = 5 s
Formula
Substitution
a = (45 - 15) / 5
a = 30 / 5
a = 6 km/s
Answer:
it is known as SURFACE TENSION
Explanation:
SURFACE TENSION is the property of water where the water can resist the force from above the 'surface' of the water. The Pond Skater is so light in weight that it doesn't break this tension at all allowing it to 'walk on water'
HELLO AND HOPE THIS HELPS!!
As the sphere moves in the liquid, it experiences a viscous force upwards that tries to resist its downward motion caused by gravity(it's own weight). This viscous force gradually increases with depth, as the speed rises(because the weight causes a positive acceleration in it's direction). At a point, the viscous force upwards becomes exactly equal to the weight downwards. Then the sphere reaches equilibrium. It doesn't have any external force acting on it, so it can't have any acceleration. So, it's velocity becomes constant, and this velocity is known as the terminal velocity.
