Answer:
Explanation:
B. -3.0
C. 48/6
D. 48/5
Answer:
The answer is D.
Explanation:
A integer can be positive, negative, or 0. So by simplifying all the fractions (making them into mixed numbers) we can find out that D results in a decimal, which is not a integer.
Answer:
The torque about the origin is 5.0 N.
Explanation:
To calculate the torque (τ) about the origin, you need to know both the force (F) and the position vector (r) from the origin to the point where the force is applied. The formula for torque is:
τ = r × F
Where:
- τ is the torque vector.
- r is the position vector.
- F is the force vector.
In this case, you're given the force vector F = 5.0 y N, where "y" represents the unit vector in the y-direction.
Assuming that the particle is located at a position where the position vector r is given as (x, y), you need to express the position vector in terms of unit vectors. Since the force is applied along the y-axis, you can write the position vector as:
r = x i + y j
Now, you can calculate the torque:
τ = r × F
τ = (x i + y j) × (5.0 y N)
When you take the cross product, the component of the position vector along the direction of the force will contribute to the torque. In this case, only the y-component of the position vector (y j) is along the direction of the force (5.0 y N).
So, the torque about the origin is:
τ = y (5.0 y N)
Now, you can calculate the magnitude of the torque:
|τ| = |y (5.0 y N)| = 5.0 |y|^2 N
The magnitude of the unit vector "y" is 1, so:
|τ| = 5.0 N
The torque about the origin is 5.0 N.
b. False
Correct answer choice is :
A) True
Explanation:
Lipoproteins are essentially a hub full of fat and cholesterol, along with a lipid layer that includes proteins named apolipoproteins. There are many kinds of lipoproteins, but the two most prominent ones are called Low-Density Lipoprotein and HDL.LDL particles are seldom related to as bad lipoprotein because of concentrations, dose-related, associated with atherosclerosis change. High-density lipoproteins (HDL) get fat molecules from the body's cells and take it back to the liver.
Answer:
It is because some of the heat is lost in the surroundings.
Explanation:
To calculate the specific heat of the metal, the following steps are performed.
Take a piece of metal whose mass and the initial temperature is known.
Now take a beaker filled with some measured amount of water and the temperature of water is known.
Drop the heated metal piece in the water so that the equilibrium is reached.
According to the principle of calorimetery,
Heat lost by the metal = heat gained by the water
here, some of the heat is lost in the surroundings so we don't get the correct value of the specific heta of the metal.
Temperate
Maritime
