Answer:
Zero Acceleration.
Explanation:
If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s.

<h2>Answer </h2>
The torque is 60 Nm.
<u>Explanation</u>
The torque of a system whose force is 30 N and the length is 2 m, then the torque is 60 Nm. The formula for torque is ( Force ) x ( moment arm ). Hence by putting values in the formula, torque = ( 30 N ) ( 2 m) which is equal to 60 Nm. The unit for torque is newton-meter (Nm). Torque is the turning effect or the force which tends to move the object in a circle and tends to rotate around a circle. Torque is a vector quantity.
The SI base units for torque is kg ⋅ m 2 ⋅ s − 2.
The density of a cube that has a mass of 12. 6 and a measured length of 4.1 cm is 0.18 kg/cm³
Density=mass/volume
mass=12.6
volume=68.9
density=12.6/68.9
density=0.18 kg/cm³
Density is defined as a material substance's mass per unit volume. Density is described by the equation d = M/V, where d stands for density, M for mass, and V for volume. Grams per cubic centimeter is the unit of measurement for density. For instance, compared to Earth's density of 5.51 grams, water has a density of 1 grams per cubic centimeter . Another way to express density is in kilograms per cubic meter (in meter-kilogram-second or SI units), It is easy to determine the relationship between mass and volume using density. For instance, the formula for determining a body's mass is M = Vd, while the formula for determining a body's volume is V = M/d.

Answer:
0.05J
Explanation:
Since the total energy is conserved I.e the mechanical energy, the energy present in the system are kinetic energy, potential energy and the gravitational potential energy. The expression for this energy is written as
Kinetic Energy=1/2MV^2
Potential Energy=1/2Kx^2
Where K is the spring constant and X is the extension the spring experience.
Gravitational Energy=mgh
Where m=mass, g=gravity constant and h=height
Hence for a spring with spring constant 10N/m and extension 0.1m the potential energy can be calculated as
PE=1/2Kx^2
If we substitute values we arrive at
PE=1/2×10×0.1^2
PE=0.05J
