Jeff is driving a remote controlled car around his living room. The car has a mass of 770 g. Jeff drives the car with a velocity of 4.1 m/s. What is the momentum of the car?
Answer:
3.16kgm/s
Explanation:
Given parameters:
Mass = 770g
Velocity = 4.1m/s
Unknown:
Momentum of the car = ?
Solution:
To solve this problem, we use the equation below:
Momentum = mass x velocity
Convert the mass to kg;
770g to kg = 0.77kg
Now;
Momentum = 0.77 x 4.1 = 3.16kgm/s

How much power does a toaster have if it does 1,000 joules of work in 30 seconds?
Answer:
33.33Watts
Explanation:
Given parameters:
Work done = 1000J
Time taken = 30s
Unknown:
Power = ?
Solution:
To solve this problem, we must understand that power is the rate at which work is done.
So;
Power = [tex]\frac{Work done }{time}[/tex]
Now insert the parameters:
Power = [tex]\frac{1000}{30}[/tex] = 33.33Watts

a substance that vigorously reacts with most metals to produce hydrogen, readily conducts electricity, turns litmus red, and has a pH less than 7; typically corrosive or sour-tasting.
A: suspension
B: base
C: acid
D: colloid
Answer:
C. Acid
Explanation:
If you have chemistry classes and performed experiments regarding acids and bases, you would physically tell it's acid if the lithmus paper turned red and base if it turned blue. Also, in the pH level chart, there are only two characteristics--acidic and basic. Since it has less than 7 pH, it is definitely acid. Plus, remember the taste of some vitamin C tablets? It has a sour taste to it, isn't it? This is because of ascorbic acid.
The given properties are indicating the substance is acid. Therefore, option (C) is correct.
What are acids and bases?An acid can be described as any substance that is capable of losing a proton to another substance. A base can be described as a molecule or ion that can accept a hydrogen ion from an acid.
Acidic substances can be identified by their sour taste. Acid is usually a molecule that donates an H⁺ ion and can be energetically favorable after a loss of an H⁺ ion. Acids are also capable to turn blue litmus into the red.
Bases can be characterized by a slippery texture and a bitter taste. A base that can be dissolved in water as an alkali. When bases and acids react, they form salts and water. Bases can turn red litmus into blue.
The acid reacts vigorously with most metals to form hydrogen. Acidic substances have pH of less than 7.

A car which is traveling at a velocity of 1.6 m/s undergoes an acceleration of 9.2 m/s over a distance of 540 m. How fast is it going
after that acceleration?
Answer:
Vf = 99.7 m/s
Explanation:
In order to find the final velocity of the car, we will use the third equation of motion. The third equation of motion is given as follows:
[tex]2as = V_{f}^{2} - V_{i}^{2}[/tex]
where,
a = acceleration of the car = 9.2 m/s²
s = distance traveled by the car = 540 m
Vf = Final Speed of the car = ?
Vi = Initial Speed of the car 1.6 m/s
[tex]2(9.2\ m/s^{2})(540\ m) = (V_{f})^{2}-(1.6\ m/s)^{2}\\V_{f}^{2} = 9936\ m^{2}/s^{2} + 2.56\ m^{2}/s^{2}\\\\V_{f} = \sqrt{9938.56\ m^{2}/s^{2}}[/tex]
Vf = 99.7 m/s
In the reaction _S+302 +2SO3, what coefficient should be placed in front of the S to balance the reaction?
A. 1
B. 2
C. 3
D.5
Answer:
B. 2
Explanation:
The reaction expression is given as:
_S + 3O₂ → 2SO₃
Now let us balanced the expression;
On the product side we have 2 moles of S
On the reactant side we should have 2moles of S
So, we put the coefficient 2 to balance the expression;
We have 6 moles oxygen on both sides

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.
