What is the magnitude of the largest net force that can be produced by combining a force of 6.0 N
ololo11 [35]

Answer:

10N

Explanation:

The formula for calculating the resultant is expressed as;

R = √F1²+F2²

F1 and F2 are the forces

Given

F1 = 6.0N

F2 = 8.0N

R = √6²+8²

R = √36+64

R = √100

R = 10.0N

Hence the magnitude of the net force is 10N

How much energy must be added to a 2-kg piece of glass with a specific heat
MAXImum [283]

Answer:

51520J

Explanation:

The energy added to the piece of glass is also called heat needed to increase its temperature from 10°C to 50°C and it depends on the mass, specific heat capacity and the change in temperature.

Q=m.c.ΔT

Q=(2kg).(644J/(kg°C)).((50°C)-(10°C))

Q=51520J

Why do students and scientists construct scale models of natural phenomena? (1 point) Oto define new units of measurement O to c
KATRIN_1 [288]

Students and scientists construct scale models of natural phenomena to better observe patterns and relationships.

What is natural phenomena?

Things that happen naturally—phenomena—occur or show up without human intervention. Gravity, tides, moons, planets, volcanic lightning, starling swarms, ant armies, sandstorms, biological processes and oscillation, among countless more events, are examples of natural phenomena.

Scientists and students  use models to help them visualize their current understanding of a system in the condition that it is in right now.

In this reaction diagram which part represents the doffrence in energy between the reactants and the products?
Annette [7]

Answer:

The correct answer is - option C. G.

Explanation:

In this reaction diagram, there is a representation of the reaction profile. The reaction profile shows the change that takes place during a reaction in the energy of reactants or substrate and products. In this profile, activation energy looks like a hump in the line, and the minimum energy required to initiate the reaction.

The overall energy of the reaction, including or excluding activation energy depends on the nature of the reaction if it is exothermic or endothermic. and products are represented by the G which shows the difference between the energy of the reactants and products.
