The potential energy is 4.10 J
Explanation:
The potential energy of a body is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object relative to the ground
For the lemming in this problem we have
m = 0.078 kg is its mass
h = 5.36 m is the height above the ground
is the acceleration of gravity
Solving the equation,

Answer:
Temperature, T = 1542.10 K
Explanation:
It is given that,
The black body radiation emitted from a furnace peaks at a wavelength of,
We need to find the temperature inside the furnace. The relationship between the temperature and the wavelength is given by Wein's law i.e.
or
b = Wein's displacement constant
T = 1542.10 K
So, the temperature inside the furnace is 1542.10 K. Hence, this is the required solution.
Answer:
magnitude of vector is 276.19 kg m/s
Explanation:
The initial momentum is vector of magnitude
And driven in a coherent manner with initial vector.
same magnitude is momentum after the impact, but it is oriented perpendicularly to initial momentum vector.
So, you have 2 momentum vector of specified magnitude perpendicular to one another.
The contrast between such two vectors is a right angle triangle hypotenuse of 195.3 sides
magnitude of vector is
