Answer:
Answer; v= 1.2654m/s
T= 110.76N
Explanation:
Apply Momentum Principle
Fdtro - Mgridt = Iow +Mvr
Fdtro - Mgridt = mK2 v/r1 + Mvr1
85 x 3x 0.345 -11 x 9.81 x 0.23 x 3 =30 x 0.25 x 0.25 x v/0.23 + 11 x v x 0.23 =
v = 1.2654m/s
To find the timed average value
Tdt -Mgdt =MV
T x 3 - 11 x 9.81 x 3 = 11 x 0.778
T= 110.76N
The answer is B(t) = constants x I(t)
Please take precaution on the point that it is an independent field of its radial position, if the point is measured well in the solenoid. (also the radial position is the axis of its symmetry)
The key projectile motion is that gravity allows downward only
Answer:5.17 m/s
Explanation:
Given
let u be the speed at cliff initial point
range over cliff is 1.45 m
and range of projectile is given by
u=3.77 m/s
Conserving Energy
Kinetic energy=Kinetic energy +Potential energy gained
Let v be the initial velocity
The answer is D. Blackbody radiation. The piece of iron glows red because its temperature is around 1000 K, then yellow because its temperature is around 2800 K, and then white because its temperature is around 5500K. This shows that the spectrum of the radiation is determined by absolute temperature, as when the temperature of a blackbody radiator increases, the peak of the radiation curve moves to shorter wavelengths.
