Here,
Load distance (Ld) = 30 cm
Effort distance (Ed) = 60 cm
Load (L) = 200N
Effort (E) = ?
Now, By using formula,
or, E * Ed = L * Ld
or, E * 60 = 200 * 30
or, E = 6000/60
◆ E = 100N
This is a Right answer...
I hope you understand...
Answer: V = 67808m/s
Explanation:
Parameter given
E = 1.63*104V/m
B = 2.50*10-3T
V = E/B
Velocity of the beam of electron = (Electric field/Magnetic field)
V = (1.63*104V/m) ÷ (2.5*10-3T)
= 169.52/ 0.0025
V= 67808m/s
D. 100 kilometers cuz the more kilometers the better the altitude!!!
Answer:
The tension is:
Explanation:
We know that the centripetal force is:
And the tension will be equal to the centripetal force at this point, so we have:
<u>a(c) is the centripetal acceleration.</u>
<u>v is the tangential speed (10 m/s)</u>
<u>R is the radius (1.6 m)</u>
<u>m is the mass of the ball (2 kg)</u>
Therefore, the tension will be:
