Answer:
An increase in the mass on the string will cause an increase in the period.
Explanation:
We'll begin by writing an expression showing the relationship between the period and mass. This is shown below:
T = 2π√(m/K)
Where:
T is the period of oscillation.
m is the mass of the object.
K is the spring constant.
T = 2π√(m/K)
From the above formula:
The period (T) is directly proportional to the square root of mass (m) and inversely proportional to the square root of the spring constant (K). This implies that an increase in the mass of the object on the spring will result in an increase in the period of oscillation and a decrease in the mass of the object will also decrease the period of oscillation.
Drag is passive, therefore it does not act on gravity. Drag is a mechanical resistance to motion. If the motion in question was induced by gravity drag it can impede that motion, but has no effect on the gravity.
hope this helps!
Answer:
i) The reactants are sodium sulphate and barium chloride
ii) The products are barium sulphate and sodium chloride.
Explanation:
In chemistry, a chemical reaction occurs when one or more chemical substances usually referred to as REACTANTS undergoes some processes and is converted to one or more different substances known as PRODUCTS.
From the question:
Na2SO4 + BaCl2 ⟶ 2NaCl + BaSO4
The above balanced equation represents the chemical reaction between sodium sulphate and barium chloride. Both are the reactants because they where the substances that passed through a process ( this involves the breaking of bond that held them together).
The PRODUCTS are barium sulphate and sodium chloride because they are the substances that presented at the end of the chemical reaction.
Answer:
I believe it's the bottom left :)
Explanation:
Answer:
V=14
Explanation:
PE=KE
mgh=1/2mv^2
2(9.8)10=1/2(2)v^2
(radical) 196= (radical)v
V=14
