Answer:
Magnetic force, 
Explanation:
It is given that,
Velocity of proton, 
Angle between velocity and the magnetic field, θ = 53°
Magnetic field, B = 0.49 T
The mass of proton, 
The charge on proton, 
The magnitude of magnetic force is given by :
So, the magnitude of the magnetic force on the proton is 
. Hence, this is the required solution.
Answer: an element; a compound
A compound is a molecule with at least two kinds of atoms. Since iron is only containing Fe then it shouldn't be a compound.
After iron got rust reaction, it will have oxygen make it become iron oxide. The iron oxide having Fe and O so it is a compound.
The spring formula:
Force = - (spring constant) · (distance stretched or squashed)
6 N = - (spring constant) · (33 cm)
= - (0.33 m) · (spring constant)
Spring constant = - (6 N) / (0.33 m)
= - 18.18 N/meter .
The negative signs means that the spring always wants to go in the
opposite direction from where you forced it, and return to its relaxed
length. If you stretch it, it tries to get shorter, and if you compress it,
it tries to get longer.
Answer: Sound Energy
Sound Energy
Explanation:The vibrations produced by the ringing bell causes waves of pressure that travel or propagate through the medium that is air. Sound energy is a form of mechanical energy that is generally associated with the motion and position of the ringing bell.
