Answer: You can die from either one.

Both conditions kill brain cells.

Explanation:

Alzheimer is a disease which affects the brain. In this the memory and thinking skills of the person get slowly destroyed. This involves the damage of the brain cells. It develops typically in the age of 60s and more. This disease can be lethal.

A stroke is an attack of brain, in this the vital flow of blood and oxygen to the brain gets stopped. The brain cells die as a result of this. This can lead to death.

7) T F If two forces of equal magnitude act on an object that is hinged at a pivot, the force acting farther from the pivot must
saul85 [17]

Answer:

False

Explanation:

The torque exerted by a force is given by:

\tau=Fd sin \theta

where

F is the magnitude of the force

d is the distance between the point of application of the force and the pivot

\theta is the angle between the directions of F and d

We see that the magnitude of the torque depends on 3 factors. In this problem, we have 2 forces of equal magnitude (so, equal F). Moreover, one of the forces (let's call it force 1) acts farther from the pivot than force 2, so we have

d_1 > d_2

However, this does not mean that force 1 produces a greater torque. In fact, it also depends on the angle at which the force is applied. For instance, if the first force is applied parallel to d, then we have

\theta_1 =0\\sin \theta=0

and the torque produced by this force would be zero.

So, the statement is false.

Why can we use regular air to
kvasek [131]

Answer:

The usual way to do this is to pass oxygen gas from a compressed gas cylinder through a coil of hollow copper pipe which is submerged in liquid nitrogen. The copper coil is a good conductor of heat and has a large surface area. Liquid oxygen is then usually collected in a thermos flask.

4. Joe and his brother Bo have a combined mass of 200.0 kg and are zooming along in
puteri [66]

Answer:

Joe & Bo's car: 200.0 kg + 100.0 kg = 300.0 kg; Melinda's car: 25.0 kg + 100.0 kg = 125.0 kg

so the answer is 125.0kg
