We have that the resultant equation is L=L we can say that the dimensions in the equation are consistent
From the Question we are given equation
[tex]x = vt + xo[/tex]
Generally
x = distance in meters(m)
v =velocity in m/s
t=time in secs
x_0=distance in meters(m)
Therefore
The Dimension of equation is
[tex]L=LT^{-1}*T+L\\\\L=L[/tex]
Hence, Given that the resultant equation is L=L we can say that the dimensions in the equation are consistent

can someone help me convert these?
Assuming you are supposed to write each conversion in scientific notation:
(2) 1 m = 100 cm, so
(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m
(3) 1 km = 1,000 m, so
(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m
(4) 1 m = 1,000 mm = 10³ mm, so
(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm
(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so
(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m
(6) 1 g = 1,000,000 µg = 10⁶ µg, so
(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g

a. kg (m/s) (1/s)
b. (kg/s) (m/s^2)
c. (kg/s) (m/s)^2
d. (kg/s) (m/s)

b. (kg/s) (m/s^2)=None
c. (kg/s) (m/s)^2= Power in Watt
d. (kg/s) (m/s)=Newton

a.kg (m/s) (1/s)
b. (kg/s) (m/s^2)
c. (kg/s) (m/s)^2
d. (kg/s) (m/s)

1) How many valence electrons are in the alkaline earth metal family? Do
they form cations or anions?
A)
1 valence electron, cations
B)
1 valence electron, anions
C)
2 valence electrons, cations
D)
2 valence electrons, anions
Answer:
Below
Explanation:
Alkaline earth metals have 2 valence electrons, which means that when they react with other elements, they will lose rather than gain their 2 electrons making them positive ions or cations.
So the correct answer to your question would be....
C) 2 valence electrons, cations

a 16 Watt bulb is used for 5 hrs. what is the energy consumed by the bulb
Energy = (power) x (time)
Energy = (16 watt) x (5 hours)
Energy = 80 watt-hours
or
Energy = 0.08 Kilowatt-hours
or
1 watt = 1 joule/second
5 hours = 18,000 seconds
Energy = (16 joule/sec) x (18,000 sec)
Energy = 288,000 Joules
Explanation:
A unit of electricity is represented in kilowatt-hour (KWh). To calculate units, you need to find the energy consumption. It is easy, just multiply power with time.
(16×5 ) watt-hour=80Wh.
Convert it to kilowatt-hour i.e 0.08 KWh/day.
So 0.08 KWh is the energy consumption for one day.

1. State Newton's third law of motion and write any three applications of it
Answer:
1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun. 2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
Newton's Third law: when object A exerts force on object B, object B simultaneously exert oppositely directed force of equal magnitude on object A.
1)When a bullet is fired from the gun with a certain force (action) as a reaction an equal and opposite force is exerted on the gun.
2)when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
15-3y=8
Solve for Y
Round to TWO decimal points
Answer: y = 2.33
Explanation:
Given expression
15 - 3y = 8
Subtract 15 on both sides
15 - 3y - 15 = 8 - 15
-3y = -7
Divide -3 on both sides
-3y / -3 = -7 / -3

PLEASE HELP AM GIVING 20 POINTS A worker in a factory has discovered a material that is confusing. It can be stored in a container but can also flow from one container to another. It forms powder after some time. The worker is confused and does not know which state of matter it belongs. As a student of Physics, prepare a message that will help the worker in the factory to properly classify the substance in the right state of matter.
The factory worker need to know is the state of the material at room temperature and atmospheric pressure.
Matter is anything that has mass and occupy space. Everything around is composed of matter. The material can easily be classified by considering the state of matter in which the material is found at room temperature and atmospheric pressure.
Hence, all the factory worker need to know is the state of the material at room temperature and atmospheric pressure. This will tell us whether it is a liquid, solid or gas.
