Answer:
force on the wire of section cm will be 
Direction of force on the wire will be in south direction
Explanation:
We have given current in the wire i = 1 A
Magnetic field strength B = 0.6 T
We have to find the force on 1 cm section of the wire so l = 1 cm = 0.01 m
Force on the wire containing current is equal to
So force on the wire of section cm will be
Direction of force on the wire will be in south direction
The net force is (40 Newtons) (down the road).
But 40 Newtons is not going to move a piano very enthusiastically.
The temperature increase of a substance is T=Q/m*c, where m is the mass, Q is the energy absorbed and c is the specific heat. So you can conclude that if the lead gets to a higher temperature, it must have a lower specific heat
Answer:
The ramp lands at an horizontal distance of 3.989 m
Explanation:
Range: Range is defined as the horizontal distance of a projectile from the point of projection to the point where the projectile hits the projection plane again. It is measure in meters (m)
R = U²sin2∅/g..................................... Equation 1
Where R = The horizontal distance from the end of the ramp, U = rider's speed, ∅ = the ramp's angle to the horizontal.
<em>Given: U = 6.3 m/s, ∅ = 40°, g = 9.8 m/s²</em>
<em>Substituting these values into equation 1</em>
<em>R = [6.3²sin2(40)]/9.8</em>
<em>R = (39.69×sin80)/9.8</em>
<em>R = 39.69×0.985/9.8</em>
R = 3.989 m
Thus the ramp lands at an horizontal distance of 3.989 m
