Answer:

Skew Lines

Explanation:

Two distinct lines intersect at most one point; two distinct planes intersect in at most one line. If two coplanar lines do not intersect, they are parallel/ Two lines which are not coplanar cannot intersect and are called skew lines.

Free ions. Negative ions have one extra electron, positive ions are missing an electron. Negative ions give up their extra electron easily. I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions.

When two objects interact, the change in momentum of the first object is ______ the change in momentum of the second object.

Mariulka [41]

Answer:

A. Equal to and Opposite

Explanation:

when there is no External force acting on the system of bodies then Net momentum of the system is Conserved .

Given that there are 2 bodies

Let P₁ as first object's momentum

P₂ as second object's momentum.

Total Momentum =P₁ + P₂

As there is no external force acying on the system

Change in the Total momentum is zero

so,

0 = Δ P₁ + ΔP₂

ΔP₂ = -ΔP₁

negative sign indicates opposite direction.

Both are of equal magnitude.

__________ is a type of molding in which thermoplastics are heated above melting temperature and, using an extruder, are forced

Ymorist [56]

Answer: The correct and is

D. Extrusion

Explanation:

What is extrusion?

Extrusion is a manufacturing process used to make basically pipes and hoses.

The pvc granules are melt into a liquid which is forced through a die, forming a long 'tube like' shape. The shape of the die determines the shape of the tube.

The extrusion is then cooled and forms a solid shape

Extrusion moulding is used to create products with a consistent cross-section.

A weightlifter curls a 25 kg bar, raising it each time a distance of 0.50 m. How many times must he repeat this exercise to burn

42 times must he repeat this exercise to burn off the energy in one slice of pizza.

What is energy?

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.

Energy burn by the weightlifter = potential energy

Potential energy = mgh

Potential energy = 25.(9.8)(0.50)

Potential energy = 122.5 Joule.

Assume 25% of efficiency so energy burn = 122.5*25/100

energy burn = 30.625 joule

Number of times = 1260/30.625

Number of times = 42 times.

42 times must he repeat this exercise to burn off the energy in one slice of pizza.
