URGENT PLEASE HELP!!!
Type the correct answer in the box. Spell all words correctly.
Find the amount of energy (Q) required to raise the temperature of the water in kilojoules (KJ).
Given mass of water m = 2kg = 2000g.
Temperature difference ΔΤ = T2 – T1 = 60 °C – 25 °C = 35 °C .
Specific heat of water = 4.18 J/g* °C .
Therefore, Q =
kilo joules.

Answers

Answer 1

Answer:

Q = 292.6 kJ

Explanation:

First, let's make sure all the values are in appropriate units.

C (specific heat of water) = 4.18 J/g °C

m (mass of water) = 2000 g

∆T = 35 °C

The equation for the needed amount of energy is:

Q = m • C • ∆T

So, we simply multiply the given values:

Q = 2000 • 4.18 • 35

Q = 292600 J

If we want the answer in kilojoules (kJ), we simply divide the value in joules with 1000:

Q = 292600 / 1000 = 292.6 kJ

I hope this helps.

Explain why Chloe's design needs to be redone in the following scenario, and recommend the techniques she needs to include in her sketches.
Chloe has drawn a design of a new supermarket She has added all of her detail to one isometric sketch. The design was not done to scale, and the construction team is not sure how large the
building will be once it is complete.

Answers

Answer:

The correct answer includes that her sketch should also include an orthographic view. She also needs to incorporate ratios to proportions so the team will know the scale of the design. She can use customary units for her measurements, as well as an engineer’s scale and a computer program to assist her with the dimensions.

the stiffness, or tension of a spring is called what

Answers

Answer: sprung Weight

Explanation: Spring Rate. refers to the stiffness, or tension, of a spring. Sprung Weight. the weight of the parts that are supported by the springs and suspension systems.

Simply said, springs of one kind or another, such as coiled springs, air springs, and Belleville springs, sustain the sprung weight of a vehicle. As wheels drive over bumps, potholes, and other obstacles, unsprung weight rises and falls with them.

What the stiffness, or tension of a spring?

The part of the vehicle's overall mass that is carried by the suspension, as well as in most applications roughly half of the suspension's weight. It is referred to as sprung mass (or sprung weight) in vehicles with suspensions like cars, motorcycles, or tanks.

Spring rate. Relates to the tension or stiffness of a spring. Lifted Weight. The mass of the components that the suspension and spring systems are designed to support.

When you are climbing a hill on a bike with different speeds, why does it seem like you are pedaling a lot to cover a short distance? What happens if you switch to a higher gear in hopes of not having to pedal as much?

Answers

It seems like your pedaling a lot because it takes more energy and is way slower than a regular road. It you switch to the higher gear it will make you go slower because it is made for going down hill or going high speeds and a lower gear will help you more cause its easier and it will make it go faster.

The reason why it seems you have to cover a short distance when pedaling up the hill is explained in Paragraph 2 below.

What will happen if you switch to a higher gear hoping you wouldn't pedal too much is explained in paragraph 3 below.

Bikes are usually configured in such a way that the mechanical advantage which is the ratio of output force to input force will increase when there is an increase in resistance like the question  shows by climbing a hill.

Now, since there is resistance from climbing the hill on the bike, it means that you must increase your effort by completing more revolutions since the bike tires itself would not complete that much revolutions required to counter the trade off distance.

Finally, if you decide to switch to a higher gear it means it will become very difficult to pedal since you need power to do so.
