Sample Response: If temperature and surface area increase, then the time it takes for sodium bicarbonate to completely dissolve will decrease, because increasing both factors increases the rate of a chemical reaction.
Pressure is the force acting per unit area and increases with increase in the weight of a body.
<h3>What is pressure?</h3>
Pressure is defined as the force acting per unit area of a body.
Pressure depends upon the amount of force on an object and the size of the area the force pushes or pulls on.
The greater the amount of weight pressing on an object, the greater the amount of pressure.
Of the following objects air, ice, plastic, and gold, gold is the most dense.
A dense object will produce more pressure than one that is not dense since it exerts a greater force per unit area.
Solids exert pressure because gravity is pulling downward on the object.
It is not true that the human body has more pressure sensors in the legs than in the fingertips as pressure sensors are more in fingertips.
Therefore, pressure is the force acting per unit area and increases with increase in the weight of a body.

When two waves intersect, they interfere and dan at the crossing point one resulting from well-defined characteristics - the combination of the two-product, but continue unchanged one to the other, each conveying his energy.
We know,
V= f× wavelength
10.5= f×0.15
f=10.5/0.15
f= 70 Hz
