Answer:
The force required is equal to
.
Explanation:
We know that
Torque = force × perpendicular distance
= F × R = I×
I = M×
From above equation
.............. 1
We know that
...........................2
Given that t= 2 sec


From equation 1 and 2 , we get
F =
= 
Upon substituting the above values we will be getting
F = 
E force needed to accelerate a 68 kilogram-skier at a rate of

m
s
2
is 81.6 Net forces.
Explanation:
Take the mass(68kg) and the acceleration of the skier(
1.2
m
s
2
) and multiply them together

Answer:
Explanation:
The direction of propagation of electromagnetic wave
is given by the direction of vector E x B where E is electrical field , B is magnetic field .
Given Electric field = E i because it is along x axis
Magnetic field = Bj because it is along y axis
E x B = Ei x Bj
= EB k .
so direction of E x B is along k direction or z - axis so wave is propagating along z - axis .
