The use of drugs to treat disease is called medication
Answer:
B
Explanation:
Wave length is the height perpendicular verically of a wave
Answer:
x ≤ 3.6913 m
Explanation:
Given
Mrod = 44.0 kg
L = 4.90 m
Tmax = 1450 N
Mman = 69 kg
A: left end of the rod
B: right end of the rod
x = distance from the left end to the man
If we take torques around the left end as follows
∑τ = 0 ⇒ - Wrod*(L/2) - Wman*x + T*Sin 30º*L = 0
⇒ - (Mrod*g)*(L/2) - (Mman*g)*x + Tmax*Sin 30º*L = 0
⇒ - (44*9.8)*(4.9/2) - (69*9.8)*x + (1450)*(0.5)*(4.9) = 0
⇒ x ≤ 3.6913 m
Answer:
The absolute potential 4.0 m away from the same point charge is -50 V.
(A) is correct option.
Explanation:
Given that,
Distance = 2.0 m
Potential = -100 V
Absolute potential = 4.0 m
We need to calculate the charge
Using formula of potential

Where, V = potential
q = charge
r = distance
Put the value into the formula



We need to calculate the potential
Using formula of potential



Hence, The absolute potential 4.0 m away from the same point charge is -50 V.
