Theodore is 170 centimeters from the finish line when Alvin crosses it.
The total distance is 451 cm, so we can find the time that takes Alvin to crosses the finish line as follows:
[tex] v_{a} = \frac{x}{t} [/tex] (1)
Where:
[tex] v_{a}[/tex]: is the speed of Alvin = 19.28 cm/s
x: is the total distance = 451 cm
t: is the time that takes Alvin to crosses the finish line =?
By solving equation (1) for t, we have:
[tex]t = \frac{x}{v} = \frac{451 cm}{19.28 cm/s} = 23.4 s[/tex]
Now, after 23.4 seconds have elapsed, Theorode has traveled the following distance ([tex]x_{t}[/tex]):
[tex] x_{t} = v_{t}*t [/tex]
Where:
[tex]v_{t}[/tex]: is the speed of Theodore = 12 cm/s
[tex] x_{t} = v_{t}*t = 12 cm/s*23.4 s = 281 cm [/tex]
The distance (d) that Theodore needs to travel to cross the finish line is:
[tex]d = x - x_{t} = 451 cm - 281 cm = 170 cm[/tex]
Therefore, Theodore is 170 centimeters from the finish line when Alvin crosses it.

A roller coaster’s velocity at the top of a hill is 10 m/s. Two seconds later it reaches the bottom of the hill with a velocity of 26 m/s. What was the acceleration of the coaster? [3]
Answer:
8 m/s²
Explanation:
a = [tex]\frac{v-v0}{t}[/tex]
a = (26 - 10)/2 = 8 m/s²

Why do we use sharp pointed needle while stiching cloths ? physic
Answer:
Explanation:
A blunt needle won't get the job done as it won't pass through the fabric well
True or false: it would take 100 years on a space shuttle to reach the closest galaxy
1. A car weighs 1000kg, you can push it .05 m/s2, how much force (F) are you applying
to the car? Here we use F=MA:
F= 1000 x .05
F= 50 newtons
Mass of the car (m) = 1000 Kg
Acceleration (a) = 0.05 m/s^2
Let the force we are applying to the car be F N.
By using the equation,
F = ma, we get
F = 1000×0.05 N = 50 N
Answer: We are applying 50 N force to the car in the direction of motion.

If you touch the two probes together while the DMM is set to resistance, what will happen?
The meter will read 0 ohms
The meter will short circuit and trip a protective circuit
The meter will read infinite ohms (as high as its scale goes)
The meter will show the equivalent voltage of the meter's internal battery
If the meter's battery is good and the meter is working OK, it should read zero ohms.
Most meters have a little adjustment wheel on the side to SET the reading to exactly zero when the probes are touched together.
HELP ME!!! Explain why an object moves if the action-reaction forces are equal.
Answer:
explanation is below
Explanation:
Equal and opposing forces acting on the same object are referred to as balanced forces. That is why they cancel each other out. Action-reaction forces do not cancel out because they are equal and opposite forces acting on different objects. In fact, they frequently cause movement.
Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

At a crime scene, a CSI investigates a substance on the ground, she finds a testable question and ponders to herself about what the substance is and goes to her lab.

if you know the time it took an object to travel between two points and the position of the object at the points, can you determine the object's instantaneous velocity
Answer:
Yes
Explanation:
[tex]v = \frac{ds}{dt} \\ where \: we \: need \: to \: know \\ \: change \: in \: displacement \\ \: and \: the \: time \: taken[/tex]
if you know the time it took an object to travel between two points and the position of the object at the points, then we can determine the object's instantaneous velocity by using the differential rate of the displacement function with respect to the time.
Instantaneous velocity = [tex]\frac{dS}{dt}[/tex]
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
velocity= displacement / time taken
for instantaneous velocity = [tex]\frac{dS}{dt}[/tex]
Thus, If you know how long it took an item to go between two places and where it was when it got there, you can use the differential rate of the displacement function with respect to time to calculate the object's instantaneous velocity.

if the light is both wave and particle ..
then when light is said to be wave and when it is said to be particle ?
Answer:
Consider electrons incident on a Young's double slit
If one slit is covered, the electrons will form a maximum, on the screen, as if they were particles incident on the screen
If both slits are open, the pattern formed on the screen will be the same as if a wave were incident on the screen, even tho electrons are slowed to the point that only 1 electron is incident on the screen at one time.
That means that the electron interferes with itself to create the interference pattern on the screen, and there is no way to determine which slit the electron went thru without destroying the interference pattern.
Some students collect some drops of water from a leaking tap.
The students measure the volume of the water they collect.
State the term for the equipment that is suitable for measuring the volume accurately.
Explanation:
The concept of temperature has evolved from the common concepts of hot and cold. Human perception of what feels hot or cold is a relative one. For example, if you place one hand in hot water and the other in cold water, and then place both hands in tepid water, the tepid water will feel cool to the hand that was in hot water, and warm to the one that was in cold water. The scientific definition of temperature is less ambiguous than your senses of hot and cold. Temperature is operationally defined to be what we measure with a thermometer. (Many physical quantities are defined solely in terms of how they are measured. We shall see later how temperature is related to the kinetic energies of atoms and molecules, a more physical explanation.) Two accurate thermometers, one placed in hot water and the other in cold water, will show the hot water to have a higher temperature. If they are then placed in the tepid water, both will give identical readings (within measurement uncertainties). In this section, we discuss temperature, its measurement by thermometers, and its relationship to thermal equilibrium. Again, temperature is the quantity measured by a thermometer.

H² = B² × L²
H² = (9.2)² × (5.2)²
H² = 84.64 × 27.04
H² = 2288.6656
H = √ 2288.6656
H = 47.84
Answer:
Use Pythagorean theorem
19) A² + B² = C²
5.2² + 9.2² = C²
C = √111.68
C = 10.567875...
C ≈ 10.6
21) A² + B² = C²
B² = C² - A²
B² = 7.2² - 5.3²
B = √23.75
B = 4.873397...
B ≈ 4.9
