<u>Answer:</u> The acceleration of the object is 2m/s^2. If net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
<u>Explanation:</u>
Force is defined as the product of object's mass and acceleration.
Mathematically,
F = ma ......(1)
or,
a = F/m .....(2)
where,
F = Force exerted on an object = 60N
m = mass of an object = 30kg
a = acceleration of the object = ?
Putting values in above equation, we get:
a = 60 kg.m/s^2/30 kg = 2m/s^2
The acceleration of the car is 2m/s^2.
From equation 2, it is visible that acceleration is directly proportional to force. This means that \if force increases, acceleration also increases.
And acceleration is inversely proportional to mass of the object. This means that if mass increases, the acceleration decreases.
Hence, if net force increases, acceleration will also increase and if mass increases, the acceleration will decrease.
Essential amino acids
Amino acids are the molecules that make up proteins when they are linked up. There are certain essential amino acids, namely they are <span>histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
All of these must be obtained from one's diet. If they are not, the body will use existing proteins, such as muscle mass, to obtain them.</span>
Answer: the option 4) 2.0 mL of 10.5 M H₂O₂, where H₂O₂ has a molar mass of 34 g/mol.
Its concentration is 10.5 M.
Explanation:
1) The unit M means molar. It is the molarity of the solution.
Molartity is the concentration of the solution expressed as number of moles of solute per liters of solution.
The formula of molarity, M, is:
M = number of moles of solute / volume of solution in liters
2) 2.0 mL of 10 M H₂SO₄, where H₂SO₄ has a molar mass of 98 g/mol
⇒ concentration is 10 M
3) 5.0 mL of 1.0 M PbSO₄, where PbSO₄ has a molar mass of 303 g/mol
⇒ concentration = 1.0 M
4) 2.0 mL of 10.5 M H₂O₂, where H₂O₂ has a molar mass of 34 g/mol
⇒ concentration is 10.5 M
5) 100 mL of 10 M NaCl, where NaCl has a molar mass of 58 g/mol
⇒ concentration is 10 M
