Answer:
Explanation:
magnetic field B = (3 i + 8 x 2 j )x 10⁻³ T
= (3 i + 16 j )x 10⁻³ T
L = - i ( unit length of conductor )
Force F = I ( L x B ) , I is current
= 5 [ - i x ( 3i + 16 j ) 10⁻³]
= 5 ( - 16 k ) x 10⁻³
F = - 80 x 10⁻³ k
Could be very slow since they’re basically going against the current which is hard so will be going slow
C)Weight
A)An attraction between two objects that have mass
B)Force decreases as distance increases.
grav force of massive planet increases your weight
Answer:
T₁= 75.25 N : Wire tension forming angle of 52° with horizontal
T₂ = 60.49 N : Wire tension forming angle of 40° with horizontal
Explanation:
We apply Newton's first law to the holiday decoration in equilibrium
Forces acting on holiday decoration:
T₁ : Wire tension forming angle of 52° with horizontal
T₂ : Wire tension forming angle of 40° with horizontal
W= m*g= 10 kg*9.8 m/s² = 98 N : weight of the decoration
∑Fx=0
T₁x -T₂x = 0
T₁x = T₂x
T₁*cos52° = T₂*cos40°
T₁= T₂*(cos40°) / (cos52°)
T₁= 1.244T₂ Equation (1)
∑Fy=0
T₁y+T₂y -W = 0
T₁*sin52° + T₂*sin40° - 98 = 0 Equation (2)
We replace T₁ of the equation (1) in the equation (2)
1.244T₂*sin52° + T₂*sin40° - 98 = 0
0.98T₂ + 0.643T₂ = 98
1.62T₂ = 98
T₂ = 98 / 1.62
T₂ = 60.49 N
We replace T₂ = 60.49 N in the Equation (1)
T₁= 1.244*60.49 N
T₁= 75.25 N
