Explanation:
please provide a screenshot or photos of moons 1-4
Solution :
a). From Newtons second law,
F = ma
The total tension force is 2T.
∴ 2T - (m + M)g = (m+ M)a
Then
b). From the person,
F = ma
T - Mg + N = Ma
or N = Ma + Mg - T
= (63 x 9.8) + (52 x 9.8) - 600
= 617.4 + 509.6 - 600
= 527 N
Answer:
Explanation:
Person suffering from myopia is unable to see objects beyond 50 cm because far point of his vision is 50 cm . He requires a concave lens
( diverging lens ) to correct his vision .
After using the lens ,
ray of light coming from far off place will appear to be coming from 50 cm after refraction through lens so it will be focused on retina .
object distance u = ∝
image distance v = - 50 cm
focal length f = ?
1 / v - 1 / u = 1 /f
- 1 / 50 - 1 / ∝ = 1 / f
- 1 / 50 = 1 / f
f = - 50 cm
focal length is negative so len is concave.
He requires concave lens of focal length 50 cm .
Answer:
|q1|/|q2| = 1/7
Explanation:
Particle 1 experiences a force F1 due to the magnetic field, B:
F1 = |q1|*v1*B
Particle 2 experiences a force F2 due to the magnetic field, B:
F2 = |q2|*v2*B
We're given that:
v1 = 7v2
Also, the force experience by both particles are equal:
F1 = F2
=> |q1|*v1*B = |q2|*v2*B
|q1|/|q2| = v2/v1
=> |q1|/|q2| = v2/7v2
=> |q1|/|q2| = 1/7
