I do not have a calculator, but let’s think...
Imagine a ballon with a certain amount of gas. When you decrease the volume by squeezing the balloon, you increase the pressure.
Which means volume is inversely proportional to the pressure:
PV=PV
Now to speed things up because class is about to start :/
PV/T=PV/T, I think
Tip: check your units and any questions let me know
Answer:
100N
Explanation:
Given parameters:
Mass = 20kg
Acceleration = 5m/s²
Unknown:
Force needed to cause the acceleration = ?
Solution:
According to Newton's second law of motion, force is the product of mass and acceleration.
Force = ma
m is the mass
a is the acceleration
Now insert the parameters and solve;
Force = 20 x 5 = 100N
Answer:
Tangential speed, v = 314.15 m/s
Explanation:
It is given that,
Mass of the object, m = 15 kg
It is moving in a circle of radius, r = 10 m
Time period, t = 0.2 seconds
We need to find the tangential velocity of the object. It is given by :
Where
v = tangential speed
v = 314.15 m/s
So, the tangential speed of the object is 314.15 m/s. Hence, this is the required solution.
In physics, energy is the property of an object which can be transferred to other objects or converted into different form, it also the ability of the system to perform work. To determine its total energy you must subtract its Kinetic Energy and it Potential Energy. I hope this helps
