Answer:
we can use 100g of compounds as the basis.
Explanation:
If you mean what F=ma is then it is Force equals mass times acceleration.
Answer:
Because of less weight kick ball has more acceleration.
Explanation:
Acceleration of kick ball:
5 m/s
Acceleration of soccer ball:
3 m/s
Newton's second law:
According to newton's second law the acceleration of object depends upon two variables.
1) Mass of object
2) Force acting on it
Mathematical expression:
a = f/m
a = acceleration
f = force
m = mass
The force on balls are same thus the acceleration is depend upon the masses of balls.
The soccer ball has more weight that's why its acceleration is less while kick ball is lighter and thus its acceleration will more.
The answer is C When more work was done, the couch was moved further.
The mass of carbon dioxide will be 238.51g
<u>Explanation:</u>
Given:
Volume, V = 81.3 L
Pressure, P = 204 kPa
P = 204000Pa
Temperature, T = 95°C
T = 95 + 273K
T = 368K
mass of CO₂, m = ?
According to the gas law:
PV = nRT
where, R is the gas constant
n is the moles
and the value of R = 8.314 X 10³ L⋅Pa⋅K⁻¹⋅mol⁻¹
n = m/w
where,
m is the mass of the substance
w is the molecular weight
and molecular weight of CO₂ is 44 g
On substituting the value we get:
Therefore, the mass of carbon dioxide will be 238.51g
