<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.
The first major contributor to the Sun's apparent motion is the fact that Earth orbits the Sun while tilted on its axis. The Earth's axial tilt of approximately 23.5° ensures that observers at different locations will see the Sun reach higher-or-lower positions above the horizon throughout the year.
hope this helps ^^
Answer: I would usually try my BEST to get help from yt videos. I recommend using yt that give the most kindergarten type speaking technique, this is really weird to say but it helps just incase you can be stressed out about the words being given by teachers in Chemistry. And I recommend writing down the notes when they explain as well. Hope this helps!
Answer:
P = 0.979 atm
Explanation:
Given data:
Number of moles of methane = 40.8 mol
Volume of container = 1020 L
Temperature = 298 K
Pressure of gas =?
Solution:
According to ideal gas equation,
PV = nRT
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
Now we will put the values,
P = nRT/V
P = 40.8 mol × 0.0821 atm.L/mol.K × 298 K / 1020 L
P = 998.2 atm /1020
P = 0.979 atm
