Total weight = Volume × density
5) calculate weight of concrete slab by multiplying volume and their density in similar unit as Weight = Volume× density, density= 150lb/ cf, so total weight = 33 cf × 150 lb/cf = 4950 pounds or 2.475 short tons.
Answer:
132.22 N
Explanation:
Weight at the surface of a planet is:
W = GMm / r²
where G is the gravitational constant,
M is the mass of the planet,
m is the mass of the object,
and r is the radius of the planet.
On Earth:
680 N = GMm / r²
If Earth's mass and radius were changed:
W = G (7M) m / (6r)²
W = 7/36 GMm / r²
W = 7/36 (680 N)
W = 132.22 N
What diagram I can't find it.
Explanation:
∑F = ma
200 N + 250 N = (1200 kg) a
a = 0.375 m/s²
The second choice ... starts with the word "both" ... is the correct statement.
