Answer:
Corect answer is D
Explanation:
Assuming that the C
O
2 gas is behaving ideally, therefore, we can use the ideal gas law to find the pressure increase in the container by:
P
V=nRT ⇒ P=n
R
T
/V
n=no of moles of the gas = mass/molar mass
Molar mass o f C
O
2=44g/mol, mass = 44g
mole n = 1mole
T=20C=293K
R=0.0821L.atm/mol.K
P=nRT/V
P = 1 x 0.0821 x 293/2
P = 12atm
Abstract. Abstract is defined as an idea or plan but no actions are done
to pursue the idea. When setting goals, one must be certain and it should be attainable in order
to achieve the goal being set. Goals that are abstract
are often poorly written and uncertain

Answer:
6.2N force
Explanation:
According to Newton's second law of motion, force is equal to the product of the mass of a body and its acceleration. Mathematically,
Force = mass × acceleration
Given mass of bucket of water = 6.2kg
acceleration of the bucket = 1m/s²
Force exerted on the rope = 6.2 × 1
= 6.2N
