The value is
Explanation:
From the question we are told that
The uniform acceleration is
The time considered is
Generally the from kinematic equation we have that
Given that the boat started from rest , the initial velocity is u = 0 m/s
So
=>
Answer:
3.8 m/s
Explanation:
Momentum is the product of mass and velocity hence
Momentum=mv where m is mass and v is the velocity of an object
Making v the subject of the formula then
Substituting 1710 kgm/s for momentum and 450 Kg for mass we obtain
Hence the speed of dogsled team is 3.8 m/s
Answer: The force acting on the proton of charge 1.5 x10-19 C moving with velocity 1.5 x10-19 C under the influence of a magnetic field of 0.7 T will be 3.15×10^-13 N.
Explanation: To find the answer we need to know more about the Lorentz magnetic force.
<h3>What is the Lorentz magnetic force acting on the proton?</h3>- Consider a proton of charge q moving with a velocity v in a magnetic field, then the Lorentz magnetic force exerted on the proton can be expressed as,
F= q (v× B)
where,
is the angle between v and B.
- In the question, it is given that,
because, from the question it is clear that the proton is moving along x axis and the magnetic field is along the y axis.
- Thus, we can find the force acting on the proton as,
Thus, we can conclude that the Lorentz force acting on the proton will be 3.15×10^-13 N.
