Answer:
ans is 3
Explanation:
Mass is a measure of the amount of matter in an object. ... Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it. An object's mass is constant in all circumstances; contrast this with its weight, a force that depends on gravity.
4, because 3+1=4 and displacement is the amount of distance traveled. Hope this helps!
Answer:
Explanation:
Actual weight, Wo = 5 N
Apparent weight, W = 4.5 N
density of water = 1 g/cm^3 = 1000 kg/m^3
density of gold, = 19.32 g/cm^3 = 19.32 x 1000 kg/m^3
Buoyant force = Actual weight - Apparent weight
Volume x density of water x g = 5 - 4.5
V x 1000 x 9.8 = 0.5
V = 5.1 x 10^-6 m^3
Weight of gold = Volume of gold x density of gold x gravity
W' = 5.1 x 10^-6 x 19.32 x 1000 x 9.8 = 0.966 N
As W' is less than W so, it is not pure gold.
Work done equals force times distance
17x3=51Nm
We first calculate for the volume of each of the figure by dividing all together the dimensions of the rectangular prism.
Volume = (10 ft)(3 ft)(3 ft) = 90 ft³
Then, multiply the volume of each prism by 10 to get the total amount of cement that needs to be poured.
Total volume = (90 ft³)(10) = 900 ft³
