Answer:
Explanation:
The magnetic moment of the coil M = current x area of loop
= I x L x L
M = L² I .
Magnetic field = B
Torque = M x B
= MB sinθ where θ is angle between M and B . Direction of M is perpendicular to face of loop
Torque = MB sin90
= MB
= L² I B .
Gravitational pull changes between each planet while its the "MASS" which doesnt change
Answer:
Lowering of mass of the shot has high kinetic energy which leads to covering more distance of the shot.
There is a difference in these throws because the mass of the shot decreases which increases its velocity and as a result the shot covers more distance. First, the athlete throws the shot having 16-pound weight or mass which covers 40 feet distance.
Whereas in the second throw, he uses a shot having 12-pound it covers 50 feet distance because the mass
is lower in the second throw and the athlete can easily throw the shot which covers more distance so the second shot has more kinetic energy as well as more velocity which compels it to cover more distance so we can conclude that lowering of mass leads to covering more distance of the shot.
Answer:
Explanation:
equation of wave is given by the following equation
y = (2.6 cm) sin[1.8 - (5.8 s-1)t].
Comparing it with standard form of wave
y = A sin ( ωt - kx )
we get
ω = 5.8
2πn = 5.8
n = .92 per second
kx = 1.8
k x 6 = 1.8
k = 0.3
= 0.3
λ = 20.9 cm
