Answer:
total surface area is 432
Explanation:
Given data
base = 6
diagonals = 8
altitude = 12
to find out
total surface area
solution
we know total surface area of prism is
total surface area = lateral surface area + 2base area ..............1
so
first we calculate base perimeter i.e = 2 length + 2 width
so perimeter = 2(8) + 2(6) = 25
and area = length * width = 8*6 = 48
so lateral surface area is perimeter * height i.e
lateral surface area = 28* 12
lateral surface area = 336
put this value in equation 1 we get
total surface area = lateral surface area + 2base area
total surface area = 336 + 2(48)
total surface area is 432
Answer:
The velocity of the police car relative to earth is
Given:
time for flash generation of the inter galactic police car, t = 1.2 s
time between flashes as measured from earth, t' = 2.2 s
Solution:
Utilising Einstein's equation for time dilation to calculate the velocity of the police car, the equation is given by:
(1)
where, c = speed of light in vacuum = 
re arranging eqn (1) for velocity, v:
(2)
Now, from eqn (2)


There are two main points that should be emphasized about the different types of electromagnetic radiation. The sequence from longest wavelength (radio waves) to shortest wavelength (gamma rays) is also a sequence in energy from lowest energy to highest energy
hope this helps you!✌
Answer:
Explanation:
Given
at certain point displacement and velocity is 0.345 m and 0.54 m/s
Therefore Potential and Kinetic Energy associated is



Kinetic Energy 

Total Energy 
Total Energy is conserved hence at maximum displacement all energy will be Potential energy

where A=maximum displacement



Maximum speed occurs at equilibrium Position where Potential Energy is zero
thus 


(c)When block is at 0.2 m from Equilibrium speed then its Potential Energy is






Answer:
Distance
Explanation:
Work is the product of force and the distance moved in the same direction as the force.
