Cubic centimeters for the volume of a solid.
Liters for volume of a liquid.
Answer:
m = 47.5 Kg
Explanation:
given,
speed of skater toward north, v = 0.8 m/s
momentum of the skater in north, P = 38 Kg.m/s
mass of the skater = ?
we now,
Momentum is equal to the product of mass and velocity
P = m x v
38 = m x 0.8
m = 47.5 Kg
hence, mass of the skater is equal to 47.5 Kg.
Answer:
20.1 m
Explanation:
First, find the time it takes for the cannonball to travel the horizontal distance of 50.0 m.
Given (in the x direction):
Δx = 50.0 m
v₀ = 68 cos 25° m/s
a = 0 m/s²
Find: t
Δx = v₀ t + ½ at²
(50.0 m) = (68 cos 25° m/s) t + ½ (0 m/s²) t²
t = 0.811 s
Now find the vertical displacement after that time.
Given (in the y direction):
v₀ = 68 sin 25° m/s
a = -9.8 m/s²
t = 0.811 s
Find: Δy
Δy = v₀ t + ½ at²
Δy = (68 sin 25°) (0.811 s) + ½ (-9.8 m/s²) (0.811 s)²
Δy = 20.1 m
Sedimentary rocks become metamorphic in the rock cycle when they are subjected to heat and pressure from burial. The high temperatures are produced when the Earth's tectonic plates move around, producing heat. And when they collide, they build mountains and metamorphose.
Igneous rocks form as magma cools below ground or lava cools on the surface. Sedimentary rocks are made from the eroded particles of other rocks or from mineral deposits left when water evaporates. Metamorphic rocks form when any existing rock undergoes intense and prolonged exposure to heat and pressure.
