The amount of force that will be exerted on a box of mass 30kg and accelerates at a rate of 3m/s² is 110N.
How to calculate force?The applied force can be calculated by using the following formula:
Resultant force = Applied force - Frictional force
Acceleration = Resultant force ÷ mass of the body
Resultant force = 3m/s² × 30kg = 90N
This means that the applied force can be calculated by adding the resultant force to the frictional force as follows:
Applied force = 90N + 20N = 110N
Therefore, the amount of force that will be exerted on a box of mass 30kg and accelerates at a rate of 3m/s² is 110N.

think about what happens to your food during digestion. The food material is broken down into smaller pieces as you chew. Then it is mixed with digestive enzymes in your stomach that break it down into simple molecules to be absorbed by your body.
Is digestion a chemical change or physical change explain why
The digestion is a chemical change so the food is solid

According to the lesson, describe in detail how you would use a triple beam balance to obtain the mass of an apple.
( Put it into your words so that you can fully understand it using 2 to 3 sentences.)
So, there are three different values on a triple beam balance; There is hundreds, tens, and units. To find the weight of an apple you move the markers until it is balanced. Say that the apple weighs one hundred-fifty-seven gram, you would first move the hundreds marker to the number one hundred. Then you would move the tens marker to fifty. Last, you would move the unit marker to seven.
Answer:
To find out the weight of the object, you’ll need to slide the weight poises until the pointer is at zero again. Start with the two heavier weight poises and then use the lightest one to do the fine tuning. The HST triple beam balance and the Ohaus model are accurate to 0.1 grams.

What is the period of a sound wave when the frequency is set to max?
What is the period of a sound wave when the frequency is set to min?
Explanation:
Wave Period: The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds, e.g. one wave every 6 seconds. Fetch: The uninterrupted area or distance over which the wind blows (in the same direction).
You want to describe the harmonic motion of a swing. You find out that it take 2 seconds for the swing to complete one cycle. The swing passes through 48 degrees as it goes from high point-to-high point in its motion (passing through a center).
a. What is the period of the swing?
b. What is the frequency of the swing in hertz?
c. What is the amplitude of the swing?
Answer:
If it takes the swing 2 seconds to complete one cycle, then
that's the period of its motion ... 2 seconds.
The frequency is the reciprocal of the period ... 1/2 Hz.
('Hz' means 'per second'.)

A box has a mass of 30kg and accelerates at a rate of 3 m/s. If the force of friction on the box is 20N, how much force did YOU exert in order to move it?
The forward force is obtained to be 110 N
What is the net force?The net force is the force that actually causes an object to move. Let us recall that force is a vector quantity. This implies that the direction of the force must also be taken into account. A force has both magnitude and directions. The direction is the area towards which a force acts.
We know that the direction of the friction is opposite to that of the force that tends to move the box forward. Thus we could write that;
Net force = Forward force - Frictional force
Note that the frictional force is negative because it is acting in opposite direction to the force that moves the object forward which has been taken to arbitrarily act in the positive direction.
Net force = ma
m = mass
a = acceleration
Net force = 30 Kg * 3 m/s^2 = 90 N
Forward force = 90 N + 20 N
110 N
Hence, the forward force is obtained to be 110 N.

Water is found all three states of matter - solid, liquid, and gas. If you place an ice cube in a pan and melt it to water and then heat it to steam, this is a physical change. Why isn't this a chemical change?
Explanation:
The elemental, chemical makeup of water (that is, H₂0) is the same no matter what state of matter it is in.
Since it is not losing or gaining any atoms when it changes states of matter, it is simply a physical change.
