Answer:
m = 788.2[kg]
Explanation:
The potential energy of a body is defined as the product of mass by gravitational acceleration by height. And it can be calculated by means of the following equation.
where:
Epot = potential energy = 63405 [J]
m = mass [kg]
g = gravity acceleration = 9.81[m/s²]
h = elevation = 8.2[m]
Now replacing:
Answer:
The electric potential (voltage) produced by a point charge
, at any point in space, is given by the following equation:
Where:
is the Coulomb's constant
is the distance
The result is a scalar quantity, is defined as the electric potential energy per unit of charge and determines the electric influence exerted by the charge on that point of space.
Answer:
The total distance is 24 m.
The tiger's resultant displacement is 8 m.
Explanation:
Given that,
Width of tiger= 8 m
Tiger starts from the right side of the cage,
Paces to the left side
Then, back to the right side,
finally, back to the left
We need to calculate the total distance covered
Using formula of distance
Put the value into the formula
We need to calculate the tiger's resultant displacement
Using formula of displacement
Put the value into the formula
Hence, The total distance is 24 m.
The tiger's resultant displacement is 8 m.
