Answer:
C
Explanation:
Lifting heavy weights every day
Answer:
option B
Explanation:
It is given that in the tire the recommended pressure is 35 PSI however the current pressure is only 26 PSI which means that pressure in the tire is less than the recommended so the chances of blowout of the tire gets eliminated hence option A is not correct.
Having pressure less in the tire can lead to the Unstable handling of the vehicle.
so correct answer is option B
Explanation:
Below is an attachment containing the solution.
Answer:
first minimum distance from the center = 0.417 m m
Explanation:
given,
wavelength (λ) = 506 nm
d = 0.075 mm = 0.000075 m
tanθ = x /2
d sinθ = m λ
m=1 ( 1 st minimum )
0.000075 × sin θ = 506 × 10⁻⁹
sin θ =
sin θ = 0.00675
θ = sin⁻¹(0.00675)
θ = 0.00675
x = 0.000417 m
hence, the first minimum distance from the center = 0.417 m m
Answer:
1.The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.
