Venis rotates on it's axis more slower than Earth.
It's negative electric charge
<span>Fire extinguishers and fire blankets should always be mounted on a surface that is painted red. This is a bright color and easy to locate. It makes it much safer for people that need to find these objects on quick notice.</span>
Answer:
The gravitational potential energy the barbells have at the maximum height, is P.E. = 3680·h J = 1.10 × 10⁴ units
Where;
h = The maximum height to which he lifts the barbells
Explanation:
The given parameters are;
The amount of work done by the championship lifter in lifting the weight, W = 1.10 × 10⁴ units
The weight of the barbells lifted by the championship lifter, N = 3680 N
The gravitational potential energy, P.E., the barbells had at their maximum height of lift is given as follows;
P.E. = m × g × h
Where;
m = The mass of the barbells;
g = The acceleration due to gravity = 9.8 m/s²
h = The maximum height to which the barbells are lifted by the championship weight lifter
m × g = The weight of the barbells = 3680 N
∴ P.E. = 3680 N × h = 3680·h J
By the conservation of energy principle, work done by the championship weight lifter = The maximum gravitational potential energy gained by the barbell = The gravitational potential energy at the maximum height, P.E.
∴ The gravitational potential energy the barbells have at the maximum height, P.E. = 3680·h J = W = 1.10 × 10⁴ units
Answer:
Because they propagate due to presence of magnetic and electric field.
Explanation:
An Electromagnetic wave is a transversal wave conformed of an electric field perpendicular to a magnetic field.
Maxwell established that an electric field can generate a magnetic field and vice versa, which allows the propagation of the electromagnetic wave without a medium.
