Answer:
- apples falling from trees
- people's feet touching the ground
- sky divers moving toward the ground
- balls bending downward after being thrown
Explanation:
When a space ship is accelerating in space, there is a force known as Inertia that kicks in. Inertia will mirror the effects of gravity on the ship even if there is no gravitational field effect such that anything that would happen where there is gravity, would continue to happen.
This means that apples will fall from trees, people's feet will touch the ground, sky divers will be pulled downwards and balls will bend downwards when thrown as well. These are the same effects expected on earth where gravity pulls things towards the earth's core.
Power is equal to energy per unit time. In this case, power is proportional to energy while is inversely proportional to time,on the other hand. Given the two swimmers exerts same amount of energy but the faster swimmer just does things in faster time, then the faster swimmer should develop more power from shorter time
I think it’s C. Stroke if not then D
Answer:
The maximum force on the supporting cable is 80688 N.
The minimum force on the supporting cable is -164 N.
Explanation:
For maximum force movement of elevator is in upward direction. Thus, equation of motion is given by,
ma = T - mg
where m is the mass of elevator
a is acceleration of elevator
g is acceleration due to gravity
T is the maximum tension in the supporting cable
T = ma + mg
T = m (a + g)
T = 4100 ( 0.04g + 9.8)
T = 80688 N
This is the maximum force on the supporting cable.
For minimum force movement of elevator is in downward direction. Thus, equation of motion is given by,
ma = T - mg
where m is the mass of elevator
a= -0.04g is acceleration of elevator because elevator is moving downward
g is acceleration due to gravity
T is the minimum tension in the supporting cable
T = ma + mg
T = m (a + g)
T = 4100 ( 9.8 - 0.04g)
T = -164 N
This is the minimum force on the supporting cable.
<u>Hello and Good Morning/Afternoon</u>:
<em>Original Question: C₂H₅OH + __O₂ → __CO₂ + __ H₂O</em>
<u>To balance this equation</u>:
⇒ must ensure that there is an equal number of elements on both sides of the equation at all times
<u>Let's start balancing:</u>
- On the left side of the equation, there are 2 carbon molecule
⇒ but only so far one on the right side
C<em>₂H₅OH + __O₂ → 2CO₂ + __ H₂O</em>
- On the left side of the equation, there are 6 hydrogen molecules
⇒ but only so far two on the right side
C<em>₂H₅OH + __O₂ → 2CO₂ + 3H₂O</em>
- On the right side of the equation, there are 7 oxygen molecules
⇒ but only so far three on the left side
C<em>₂H₅OH + 3O₂ → 2CO₂ + 3H₂O</em>
<u>Let's check and make sure we got the answer:</u>
C<em>₂H₅OH + 3O₂ → 2CO₂ + 3H₂O</em>
<em> 2 Carbon ⇔ 2 Carbon</em>
<em> 6 Hydrogen ⇔ 6 Hydrogen</em>
<em> 7 Oxygen ⇔ 7 oxygen</em>
<u>Thefore the coefficients in order are</u>:
⇒ 1, 3, 2, 3
<u>Answer: 1,3,2,3</u>
Hope that helps!
