Does air resistance affect the motion of a falling object differently when the mass is greater?
mixas84 [53]
<span>NO.

Air resistance does not affect the motion of a falling object differently when the mass is greater because the mass of an object does not in any way affect the speed of falling due to gravity, and air resistance depends only on the speed of the object and its surface area.</span>

Change of 5000 c flows through a circuit in one hour. what is the current intensity?​
AleksandrR [38]

Answer:

I = 1.38 A

Explanation:

Given that,

Charge, q = 5000 C

Time, t = 1 hour = 3600 s

We need to find the current intensity. The current intensity is equal to the electric charge per unit time. It can be given by :

I=\dfrac{q}{t}

Substitute all the values in the above formula

I=\dfrac{5000\ C}{3600\ s}\\\\=1.38\ A

So, the current intensity is 1.38 A.

I need to know what is a product and a reactant in this please
Alekssandra [29.7K]

Answer:

2Mg + O2 = Reactant | 2MgO = Product

Explanation:

It is pretty simple, look:

The elements that are being added (or in the majority of the cases, the one who are in the left side) are always the Reactant.

The other side is the product of the reactants.

It is like a mathematic formula

We some the numbers to get the result, the numbers are the reactants and the result is the product.

(I hope you didn´t get confused)
