Answer:
3 cm
Explanation:
I think the question have some error because if height = 2 m = 200cm.
Volume of box = l * b * h
V = 30 cm³
b = 5 cm
h = 2 cm
l = ?
V = l * b * h
30 cm³ = l * 5 * 2
l = 30 / 10
l = 3 cm
identify two ways in which friction is not useful in science
Answer:
Friction between brakes and the wheels of a car or bicycle helps the vehicles slow down.If you do not lubricate your bike regularly with oil, the friction in the chain and axles increases.a car initially at 39.40 m/s accelerates at -3.00 m/s^2 how far has a car travel when it comes to a stop 9.35 seconds later
Answer:
499.523. meter

Precision is how close a series of measurements are to ______
Answer:
Accuracy is how close a measured value is to an accepted value. Precision is how close measurements are to one another. To make measurements, you have to evaluate both the accuracy and the precision to get a correct value.
1. Define friction, and explain why it occurs.
Answer:
The simplest way to put it is that friction is a force in which there is a resistance between material elements when they slide against each other. There is no completely accurate answer as to why friction occurs, but scientists believe that it is because of tiny bumps on the surface of a material.

An Internet connection transfers 32 kilobytes per second. How many bytes are being transferred every second?
Answer:
32,000
Explanation:
There are 1,000 bytes in each kilobyte, so therefore 32,000 bytes are transferred each second.
Calculate the molecular weight of Aluminium hydroxide
Al(OH)3 = 26.98 + [(16×3) + (1.01×3)] = 26.98 + 51.03 = 78.01 and the unit will be g/mol
Al(OH)3 = 78.01 g/molUsing the graph above determine the change in velocity between 0.0 s and 4.0 s.

to increase. Which expression relates the force to the momentum and the time taken?
The expression that relates the force to the momentum and the time taken is [tex]F =\frac{\Delta P}{t}[/tex].
Let the constant force causing change in momentum, = FLet the time of force action = t
The impulse experienced by the body at the given constant force and time is calculated as follows;
[tex]J = \Delta P = mv[/tex]
where;
ΔP is change in momentum
The force acting on a body is given by Newton's second law of motion;
[tex]F = ma\\\\F = \frac{mv}{t} \\\\Ft = mv\\\\Ft = \Delta P\\\\F = \frac{\Delta P}{t}[/tex]
Thus, the expression that relates the force to the momentum and the time taken is [tex]F =\frac{\Delta P}{t}[/tex].
