A container can hold a mass of 40 grams. If Jackson has a fake gold chain that has a density of 10 g/cm3 that occupies a space o

f 5 cm3, will the box be able to hold it? (D=M/V, V=M/D, M=DxV)

Use the formula M=D×V:

M=10 g/cm³ * 5 cm³ = 50 g

which is more than 40 grams, so the container cannot hold the chain.

A crate is pulled to the right with a force of 85 N, to the left with a force of 115 N, upward with a force of 565 N, and downwa
balandron [24]

Answer:

330.4 N and  95.2^{\circ}counterclocwise to the x direction

Explanation:

Sum of forces in vertical are equal, let movement to right and upwards be positive while left and downwards be negative

Net force in horizontal direction is 85-115=-30 N

Net force in vertical direction is 565-236=329 N

Resultant force=\sqrt {(-30)^{2}+329^{2}}=330.3649497 N\approx 330.4 N

Direction=tan^{-1}\frac {329}{-30}=-84.78986932\approx -84.8^{\circ}

180-84.8=95.2

Therefore, direction is 95.2^{\circ}counterclocwise to the x direction

An object has 90000 J of kinetic energy and is moving at 12 m/s. what is the objects mass?
Klio2033 [76]

Answer:

1250kg

Explanation:

we can solve this using the formula for the Kinetic Energy

Kinetic.Energy=\frac{1}{2}*mass*velocity^{2}\\mass=\frac{2*Kinetic.Energy}{velocity^{2}}\\mass=\frac{2*90000}{12^{2}}\\\\mass=1250kg
