After you measure the dimensions of a plot of land with a steel tape on a hot day you return and re measure the same plot on a cold day On which day do you determine the larger area for land?

On a cold day, you will measure a larger area compared to a hot day; metals expand when heated. So on a hot day, your steel ruler will also expand. Whatever you measure on a hot day will be relatively less compared to a cold day.

According to physics what is the definition of elasticity?
Elasticity, in physics, is defined as the property of a material whose dimensions can be altered by applying stress. However, the object will return to the original form.
How do bats use echolocation to determine the distance of an insect?
The distance is measured on the time it takes the sound to return to the bats ears...
What is meant by a period of a pendulum?
The period of a pendulum is a measure of the amount of time it takes to complete one full cycle and return to its starting position.
How do you calculate stiffness of a elastic material?
When a load is applied to a material it deforms. Elasticity is defined as the ability of a material to return completely to its original state after a load is removed. For example, the reason an elastic band is elastic is that it will return to its original dimensions after being stretched and released. Modulus of elasticity is the measure of this ability and is experimentally determined by measuring how much a material deforms when a given load is applied. A high modulus material is very stiff. A low modulus material is more "rubbery". Engineering calculation of deflection of a design element use Modulus of Elasticity (aka Lambda) an an input.
How can we measure the depth of sea by using SONAR?
Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !
What factors determine interest rates?

Write a c program to find the largest and second largest number out of 3 numbers?
// return the larger of any 2 numbers int larger (int a, int b) { return a>b?a:b; } // return the largest of any 3 numbers int largest (int a, int b, int c) { return larger (larger (a, b), c)); } // return the middle value of any 3 numbers int middle (int a, int b, int c) { if (a>b) a^=b^=a^=b; // swap a and b (b is now the larger of the two) if (b>c) b^=c^=b^=c; // swap b and c (c is now the largest of all three) return larger (a, b); // return the larger of a and b }
Where is the best place to install a home thermostst?
Typically, the thermostat will be mounted on a wall above your return or on wall directly across from return. The thermostat needs to be near return to measure air temp going back to your air handler to determine when the temp setting has been satisfied, then the tstat tells the system to turn off.

Are there standard dimensions for patio furniture cushions?
There are not standard dimensions. However, cushions by their nature can be squished down into a smaller size, or have ties added on to secure them in place if they are too small. Take rough dimensions before you get started shopping, and save your receipts for return of merchandise.

averaging percentage changes produce an inaccurate measure of the true rate of return because it does not consider compounding
