If the scaled-up man now stands on one leg, what fraction of the tensile strength is the stress on the femur?.

Oksanka [162]

The fraction of the tensile strength which is the stress on the femur is 1.4%.

<h3>What is Tensile strength?</h3>

This is defined as the amount of load or stress that a material can handle before it stretches and breaks.

The femur which is located in the thigh is the largest bone in the body and it exerts a fraction of 1.4% tensile strength through the stress encountered on the femur when the man stands with one leg.

A car travels along straight line for first half time with a speed of 40 km/h and the second half with a speed of 60km/h find th

Vesna [10]

Answer:

Average speed of car will be 48 km/hr

Explanation:

Let the total distance is 2d

It is given that first half of the distance car travels with a speed of 40 km/hr

So time taken to cover half of the distance $t_1=\frac{d}{40}hr$

Second half of the distance is covered with a 60 km/hr

So time taken to cover second half of the distance $t_2=\frac{d}{60}hr$

So total time to cover 2d distance $t=\frac{d}{60}+\frac{d}{40}=\frac{5d}{120}$

Average speed is the ratio of total distance to total time

So average speed $=\frac{2d}{\frac{5d}{120}}=48km/hr$

So average speed of car will be 48 km/hr

How much heat is required to raise 100 grams of water (c= 4.18) by 5 degrees Celsius?

Andrei [34K]

Answer:

Heat capacity, Q = 2090 Joules.

Explanation:

Given the following data;

Mass = 100 grams

Specific heat capacity = 4.18 J/g°C.

Temperature = 5°C

To find the quantity of heat required;

Heat capacity is given by the formula;

$Q = mct$

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

t represents the temperature of an object.

Substituting into the formula, we have;

$Q = 100*4.18*5$

Heat capacity, Q = 2090 Joules.
