Your friend wants your advice about his new transformation fitness plan. He has found a plan that sounds promising to him, but h

e wants to know what you think before he gets started. The plan is backed by several celebrities. It requires people to buy expensive, pre-packaged, microwavable food and supplements and some workout equipment. Their website promises people can lose up to 30 pounds with minimal exercise. What should you tell your friend? This is a good plan, but he should find a coupon online to reduce the cost. There is not enough information to determine whether this plan is good or not. This is not a good plan because the best bet is always healthy eating and regular exercise. This is not a good plan unless he is going to add a 100% fruit juice with his breakfast.

A 45.0-kg sample of ice is at 0.00°C. How much heat is needed to melt it? For water, Lf=334 kJ/kg and Lv=2257 kJ/kg 
Aleonysh [2.5K]

Heat required to change the phase of ice is given by

Q = m* L

here

m = mass of ice

L = latent heat of fusion

now we have

m = 45 kg

L = 334 KJ/kg

now by using above formula

Q = 45 * 334 * 10^3

Q = 1.5 * 10^7 J

In KJ we can convert this as

Q = 1.5 * 10^4 kJ

so the correct answer is D option

What is the value of x in the triangle? a 45-45-90 triangle with leg length x and hypotenuse length 4
mrs_skeptik [129]

Answer:

x = 2\sqrt 2

Explanation:

Given

Hypotenuse = 4

Required

Find x

Since the triangle is a 45-45-90 triangle, the following relationship exists

x^2 + x^2 = 4^2 --- i.e. the other legs are equal

So, we have:

2x^2 = 16

Divide both sides by 2

x^2=8

Take square roots of both sides

x = \sqrt 8

Simplify

x = 2\sqrt 2
