Hi,
The answer should be:
Vector 5
Magnatude 4
Weight 1
Mass 2
Net force 6
Force 3
Hope this helps!
Football helmets that are made with padding are believed to have reduced head injuries especially when a player accidentally collides with an object. This is because the impact of the collision is decreased due to the padding that serves as a shock absorber.
Answer:
The correct answer option is energy but not matter.
The resultant force on the system is equivalent to the difference in the weights of the chandelier and Robin Hood.
F(net) = 240g - 85g
F(net) = 155g
Robin Hood's Acceleration:
F = ma
155g = 85a
a = 17.89 m/s²
Tension = mg + ma
Tension = 85(g + a)
Tension = 2400 N
Answer:
Explanation:
Torque on a loop in a magnetic field
Maximum torque = M B
M is magnetic moment of loop and B is magnetic field
M = area x current
= 3.14 x .10² x i
Maximum torque = M B
1 x 10⁻³ = 3.14 x .10² x i x .65 x 10⁻⁴
i = 490 A
Current = 490 A.
