Answer:

Explanation: Blowing is a kind of force (push). Force can change the shape and size of an object. Example: shape or size of a spring changes on pulling or pushing it. Pulling increases it’s length while pus

ing decreases it’s length.

Force applied causes deformation in the object. It changes the relative positions of constituent particles in the crystal lattice.
As soon as that happens, the interatomic or intermolecular forces come into play and they, tend to restore the solid back to it's original shape.

This restoring force per unit area is called Stress . When external forces are removed, the internal forces tend to restore the solid back.
This property is called Elasticity .

However, no material is perfectly elastic and what happens is that, the body is not able to restore itself completely.

Goshia [24]

Answer: The answer is option B

Explanation:

The base of the pyramid represents primary producers since they help to pass on energy to consumers as we go higher in the pyramid. They are not consumers because they supply energy and do not use up energy. They are called autotrophs.

Two objects (42.0 and 21.0 kg) are connected by a massless string that passes over a massless, frictionless pulley. The pulley h
Kazeer [188]

Answer:

a = 3.27 m/s²

T = 275 N

Explanation:

Given that:

Mass m₁ = 42.p0 kg

Mass m₂ = 21.0 kg

Consider both masses to be in a whole system, then:

The acceleration can be determined as:

(m_1+m_2)a = g(m_1-m_2)

Making acceleration the subject in the above formula;

a =\dfrac{g(m_1-m_2)}{(m_1+m_2)}

a =\dfrac{9.8(42.0-21.0)}{(42.0+21.0)}

a =\dfrac{9.8(21.0)}{(63.0)}

a =\dfrac{205.8}{(63.0)}

a = 3.27 m/s²

in the string, the tension is calculated using the formula:

T = \dfrac{2m_1m_2g}{(m_1+m_2)}

T = \dfrac{2(42)(21)(9.81)}{(42+21)}

T = \dfrac{17304.84}{63}

T = 274.68 N

T ≅ 275 N

True or False: Our food has potential energy?
DanielleElmas [232]

Hello User,

Answer is yes.

Explanation

<em>At the most fundamental level, chemical energy is stored in food as molecular bonds. These molecular bonds represent potential energy, which is either very stable, such as in fat molecules, or very active and transitory, such as in ATP molecules.</em>

Hope it helps you... pls mark brainliest
