Answer:
6.21 rad/s
1.3041 m/s, 0.567 m/s²
Explanation:
= Final angular velocity
= Initial angular velocity = 0
= Angular acceleration = 2.3 rad/s²
= Angle of rotation
t = Time taken = 2.3 s
Equation of rotational motion
The angular speed is 6.21 rad/s
Linear velocity is given by
Linear velocity is 1.3041 m/s
Tangential acceleration is given by
Tangential acceleration is 0.567 m/s²
In degress the angle would be
From x axis it would be
The angle is from x axis
Answer:
b and e
Explanation:
r x F is the formula for torque.
The "turning effect" or torque happens when concentric forces rotate an object along said center.
a) False because T = Fr = Ia (a = angular acceleration)
b) True
c) False. L = Iw (w = angular velocity), which does not equal Ia
d) False. It is torque, not the product of torque and something else
e) True.
The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. It is responsible for our thoughts, feelings, memory storage and general perception of the world.
The human heart is a responsible for pumping blood throughout our body.
The job of the kidneys is to remove waste and extra fluid from the blood. The kidneys take urea out of the blood and combine it with water and other substances to make urine.
The liver has many functions, including detoxifying of harmful chemicals, breakdown of drugs, filtering of blood, secretion of bile and production of blood-clotting proteins.
The lungs are responsible for removing oxygen from the air we breathe and transferring it to our blood where it can be sent to our cells. The lungs also remove carbon dioxide, which we exhale.
Skin is important in creating a physical barrier to protect the body from pathogens.
Answer:
5 moles of O2are required, you can see it in your equation.
Explanation:
The Simple Pendulum. A simple pendulum is defined to have a point mass, also known as the pendulum bob, which is suspended from a string of length L with negligible mass ((Figure)). Here, the only forces acting on the bob are the force of gravity (i.e., the weight of the bob) and tension from the string.
