Answer:
F = 33.12 N
Explanation:
given,
first force = 15 N is oriented at 58.0° counterclockwise
second force = (−19.0 N,18.5 N)
x-component of first force = 15 cos 58.0° = 7.95 N
y-component of second force = 15 sin 58.0° = 12.72 N
second component
now,
F netx = 7.95 - 19 = -11.05 N
F nety = 12.72 + 18.5 = 31.22 N
F = 33.12 N
θ = -70.51°
Water=hydrosphere
wind=atmosphere
ice=cryosphere
organisms=biosphere
I think!!
Velocity is a vector, which includes both magnitude and direction. Negative velocity means that B is travelling in an opposite direction of A.
Answer:
-2 m/s²
8.7 m/s
Explanation:
Using Newton's second law, the sum of forces in the x direction:
∑F = ma
-120 N = (60 kg) a
a = -2 m/s²
Given:
Δx = 6.0 m
v₀ = 10 m/s
a = -2 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (10 m/s)² + 2 (-2 m/s²) (6.0 m)
v = 8.7 m/s
Answer:Although the crust is solid, the core of the Earth is surrounded by a mixture of molten iron and nickle. The magnetic field of Earth is caused by currents of electricity that flow in the molten core. These currents are hundreds of miles wide and flow at thousands of miles per hour as the earth rotates. hope it helped in someway ig idk
