If a train is moving 10 m/s, how long would it take the train to go 2200 m
Answer:
220 seconds
Explanation:
Waves are observed passing under a dock. Wave crests are 8.0 meters apart. The time for a complete wave to pass by is 4.0 seconds. The markings on the post submerged in water indicate that the water level fluctuates from a trough at 6.0 meters to a crest at 9.0 meters. Calculate the velocity of the wave.
Answer:
2 m/s
Explanation:
The crest of the wave moves 8 meters in 4 seconds, so its speed is ...
(8 m)/(4 s) = 2 m/s
Answer:
2 m/s is the answer .

What type of boundary is shown in the diagram?
Answer:Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Convergent boundaries -- where crust is destroyed as one plate dives under another.
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

The velocity of a car increases from 10 km/h to 50 km/h in 5 seconds. What is its acceleration?
Answer:
2.22m/s^2
Explanation:
equation for power work done and time
Answer:
power can be expressed as P=work/change in time,instead of P=change of energy/change in time because the change of energy is basically the work done.
Answer:
P=W/T....is the answer

A reference point allows you to determine the _____________of an object state state speed speed position position dimension
Answer:
Position.
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.
A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.
For example, a point on a map is considered to be a reference point because it represents the starting point of an object or person in motion.
Hence, a reference point allows you to determine the position an object.

On a box are the words 12 Volt : 50 mA
What is the resistor in Kilo-Ohm?
Answer:
R = 0.24 kilo-ohm
Explanation:
Given that,
Voltage, V = 12 volt
Current, I = 50 mA = 0.05 A
We need to find the resistance of the resistor. We can find it using Ohm's law. So,
V = IR
[tex]R=\dfrac{V}{I}\\\\R=\dfrac{12}{0.05}\\\\R=240\ \Omega[/tex]
or
R = 0.24 kohm
So, the value of resistance is 0.24 kilo-ohm.

What is experiment ?An experiment is a technique used to confirm or deny a hypothesis, as well as assess the possibility or effectiveness of something that has never been done before. Experiments show what happens when a certain component is modified, which sheds light on cause-and-effect relationships. The purpose and scope of experiments vary widely, but they always rely on a repeatable process and a rational examination of the outcomes. Natural experimental experiments are also a thing.
While a child may conduct simple experiments to better understand how objects fall to the ground, scientific teams may spend years conducting thorough research to increase their understanding of a phenomenon.
This experiment shows enthalpy is positive, heat is absorbed in this experiment. this breaks the atoms and it needed the energy.

A volume of 25 milliliters is the same as a volume of ____________________ cubic centimeters.
Answer:
25 cm³
Explanation:
In the conversion of units, we know that are one cubic centimeters (cm³) in a milliliter (mL) .
1 milliliter = 1 cubic centimeter
25 milliliters = 25 cubic centimeters
Therefore, a volume of 25 milliliters is the same as a volume of 25 cubic centimeters.
This ultimately implies that, the volume of an object in milliliters is equivalent to its volume in cubic centimeters.

Resistor 1 has a resistance of 10 N and
carries a current of 3 A. Resistor 2 has a resistance of
5 and carries a current of 10 A. Which resistor has
the greater potential difference?
Answer:
Resistance 2.
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage. I represents current measured in amperes. R represents resistance measured in ohms.Note: Voltage is the same as potential difference.
Given the following data;
Resistance 1 = 10 Ohms
Current 1 = 3 Amperes
Potential difference 1 = current * resistance
Potential difference 1 = 3 * 10
Potential difference 1 = 30 V
To find the potential difference in 2;
Resistance 2 = 5 Ohms
Current 2 = 10 Amperes
Potential difference 2 = 10 * 5
Potential difference 2 = 50 V
Therefore, Resistance 2 has greater potential difference.
A 1800 kg car moving south at 17.5 m/s collide with a 2800 kg car moving north. The cars stick together and move as a unit after the collision at a velocity of 5.22 m/s to the north. Find the velocity of the 2800 kg car before the collision
Answer:
v₀₂ = -2.67 m / s
Explanation:
Let's use the conservation of the moment, for this we define a system formed by the two cars.
Consider the north direction as positive and the subscript 1 will be used for car 1 and the subscript 2 for the second car
Initial instant. Before the crash
p₀ = -m₁ v₀₁ + m₂ v₀₂
Final moment. Right after the crash
p_f = (m₁ + m₂) v
p₀ = p_f
-m₁ [tex]v_{o1}[/tex] + m₂ v_{o2} = (m₁ + m2) v_{f}
v₀₂ = [tex]\frac{(m_1 +m_2) v }{m_2}[/tex]+ [tex]\frac{m_1 v_{o1} }{m_{1} }[/tex]
let's calculate
v₀₂ = [tex]\frac{(1800 +2800) 5.22 + 1800 (-17.5)}{2800}[/tex]
v₀₂ = -2.67 m / s
the negative sign indicates that the carriage moves in the opposite direction of the temperies
