approaching a dangerous intersection the driver slows her car from 40 meters per second to 15 meters per second in 5 seconds what is the acceleration
Answer:
- 5 m/s^2
Explanation:
Givens
vi = 40 m/s
vf = 15 m/s
t = 5 seconds
Formula
a = (vf - vi)/t
a = (15 - 40)/5
a = -25/5
a = - 5 m/s^2
Don't be bothered by the minus sign. It just means she is slowing down.

Show workings where necessary.
Answer:
I think the reason why ice is forming on the aluminium lumps and not the beaker, is because:
The beaker is already on the same temperature as the mixture inside it: as a result, there is no heat transfer.
on the other hand, the Aluminium Lumps is at a way lower temperature than the mixture and as a result, there is heat transfer from the water around the lumps to the aluminium Lumps itself.
turning the water into ice.
Heat is lost from the water, and gained on the aluminium.
Since the water was turned to ice.
we can say that the final temperature of the heat transfer process is 0°C.
Notice that we'll be making use of the latent heat of fusion for ice. since water is being converted to ice at 0°C.( workout is in above attachment)

A 400-kg space probe has a weight of 3,560 N on one of the above planets. According to the table
above, on which planet is the space probe? Show your work.
Answer:
Venus
Explanation:
To know the correct answer to the question, we shall determine the weight of the space probe on each planet to see which will correspond to 3560 N.
This is illustrated below:
For Mercury:
Mass = 400 Kg
Gravitational force = 3.7 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 3.7
Weight = 1480 N
For Venus:
Mass = 400 Kg
Gravitational force = 8.9 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 8.9
Weight = 3560 N
For Earth:
Mass = 400 Kg
Gravitational force = 9.8 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 9.8
Weight = 3920 N
For Neptune:
Mass = 400 Kg
Gravitational force = 11 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 11
Weight = 4400 N
For Jupiter:
Mass = 400 Kg
Gravitational force = 23.1 N/Kg
Weight =?
Weight = mass × gravitational force
Weight = 400 × 23.1
Weight = 9240 N
SUMMARY:
Planet >>>>>> Weight
Mercury >>>> 1480 N
Venus >>>>>> 3560 N
Earth >>>>>>> 3920 N
Neptune >>>> 4400 N
Jupiter >>>>>> 9240 N
From the above calculations, we can see that the weight of the space probe (i.e 3560 N) correspond to the weight on venus (i.e 3560 N)

Explanation:
The apparent height of a building 10.5 km away is 0.02 radians. What is the approximate height of the building to the nearest meter
Answer:
Approximate height of the building is 23213 meters.
Explanation:
Let the height of the building be represented by h.
0.02 radians = 0.02 × [tex]\frac{180^{o} }{\pi }[/tex]
= 0.02 x (180/[tex]\frac{22}{7}[/tex])
0.02 radians = 1.146°
10.5 km = 10500 m
Applying the trigonometric function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
So that,
Tan 1.146° = [tex]\frac{h}{10500}[/tex]
⇒ h = Tan 1.146° x 10500
= 2.21074 x 10500
= 23212.77
h = 23213 m
The approximate height of the building is 23213 m.

Explain the term the refractive index of glass is 1.5
Answer:
Refractive index of a glass is 1.5 means that the speed of light travels 1.5 times SLOWER in that glass than in a vacuum.
Explanation:
Refractive index is defined as a ratio between the speed of light in a vacuum and the speed of light in a medium. Since the refractive index is a ratio between two speeds it is a dimensionless number. For the glass, having a refractive index of 1.5, means that the speed of light travels 1.5 times SLOWER in that glass than in a vacuum.

Find an everyday situation that involves density or buoyancy and explain it.
Answer:
Explanation:
Swimming. When you go swimming, your body floats but somewhat sinks as well because we weigh less when we're in the water. We are less dense.
Or taking a bath, the soap sinks to the bottom and the washcloth somewhat floats and sinks because of the air trapped in the middle. But the rest of the washcloth is sinking because it's absorbed the water which makes it denser.

Answer:
1a: Lead atoms are heavier than aluminum atoms, which means that a given mass of lead contains fewer atoms than the same mass of aluminum. Since the heat required to raise the temperature depends on the number of atoms, it takes less heat to raise the temperature of the lead than the temperature of the aluminum.
