A weight machine ____.A) Decreases the amount of input force required

B) reduces the amount of input work

C) changes the direction of the input force

D) increases the input distance

Answers

Answer 1

Answer:

C) changes the direction of the input force

Explanation:

A weight machine measure the normal reaction of a body place on the machine.This means the force will have no acceleration. The body placed on the machine will thus exert the force due to gravity and the normal reaction will act in the opposite direction to it.

(please show work)A rock is dropped off of a cliff. It falls to the ground in 10 seconds. Answer the following questions assuming that there is no air resistance.

c. What is the instantaneous velocity of the rock just before it hit the ground?

d.Find the rock's displacement for the 10 seconds.

Answers

c. -98 m/s

The motion of the rock is a uniformly accelerated motion (free fall) with constant acceleration $g=-9.8 m/s^2$ (negative since it is downward). Therefore, we can find its velocity using the following suvat equation

$v=u+gt$

where

v is the final velocity

u is the initial velocity

g is the acceleration of gravity

t is the time

For the rock in the problem,

u = 0

So, its velocity at t = 10 s is

$v=0+(-9.8)(10)=-98 m/s$

where the negative sign indicates that the velocity points downward.

d. -490 m

Since the motion is at constant acceleration, we can use another suvat equation:

$s=ut+(1)/(2)gt^2$

where

s is the displacement

u is the initial velocity

g is the acceleration of gravity

t is the time

Substituting:

u = 0

$g=-9.8 m/s^2$

t = 10 s

We find the rock's displacement:

$s=0+(1)/(2)(-9.8)(10)^2=-490 m$

where the negative sign means the displacement is downward.

3. Three metal spoons are on a table. They are each at room temperature. If the three spoonstouch,
heat will flow among all three spoons.
heat will flow between two spoons.
no heat will flow among the spoons.
o heat will flow from the spoons to the air.

Answers

If the spoons touch, no heat will flow among the spoons. This is because they are already at thermal equilibrium with each other. This is hinted by the statement "they are at room temperature" which means they all have the same temperature. Heat only flows when there is a difference in temperature.

Surface winds on earth are primarily caused by differences in temperature.

Surface winds are displacements of air, which migrates to regions of high air pressure to pressure points that is less.

Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn: germinating and non-germinating. A germinating seed is one from which plant has started to grow. A non-germinating seed is usually dry, and a new plant has not yet emerged.The data that she gathered is displayed in the graph below.Which of the following statements are true concerning the data that Callie gathered during the lab? Choose the two that apply.
A.The germinating corn seed produced more energy than the non-germinating corn seed.
B.The non-germinating corn seed produced more carbon dioxide than the germinating corn seed.
C. The germinating corn seed consumed more oxygen than the non-germinating corn seed.
D. The non-germinating corn seed performed more cellular respiration and the germinating corn seed.
E. The non-germinating corn seed performed cellular respiration and the germinating corn seed performed fermentation.
Please I NEED the TWO ANSWERS ASAP!

Answers

The correct options are :

(A) The germinating corn seed produced more energy than the non-germinating corn seed.

(C) The germinating corn seed consumed more oxygen than the non-germinating corn seed.

information from the graph:

We can clearly see in the graph that the slope of the germinating seed is steeper than that of the non-germinating seed.
Since the germinating seed has a steeper graph, it shows that its rate of consumption of oxygen is higher than that of the non-germinating seed.
As the germinating seed consumes more oxygen, it implies that it produces more energy than the non-germinating seed.
