Answer:
The average acceleration of the car is 2.143 meters per square second.
Explanation:
Let assume that car accelerates uniformly, in that case, we can obtain the value of acceleration by using the following equation of motion:
Where:
- Initial velocity, measured in meters per second.
- Final velocity, measured in meters per second.
- Acceleration, measured in meters per square second.
- Time, measured in seconds.
Now, we clear acceleration within expression:
Initial and final velocities are now converted from kilometers per hour into meters per second:
If we know that 
, then, the average acceleration of the car is:
The average acceleration of the car is 2.143 meters per square second.
Answer:
Explanation:
Since 100C is the boiling temperature for water, for this problem we don't need to calculate the energy needed to get to the boiling point, just the heat or energy needed to vaporize the water to steam at 100C.
The formula for this is q=m(delta)
q is Joules of heat needed to vaporize the water to steam at 100C
m is mass in grams
Delta is in Joules per gram and can be looked up for water at this temperature. Here, it is approximately 2260J/g. This online lecture should help ease understanding: https://cabrillo.instructure.com/courses/10267/modules/items/256219
Therefore...
q=2.5g (2260J/g)= 5650J = 5.65kJ
I do not do Physics tutoring but am happy to answer questions here.
Answer:
(a) <em>Beat</em>: A beat defines the movement and speed of a rhythm. It describes the flow of the rhythm of a piece of music. There are various concepts related to beat such as tempo, groove and meter.
(b) <em>Subdivision: </em>Subdivision typically means dividing a large entity into smaller entities. In music, rhythms can be broken down into sub-sequences. For example, starting with a whole note, the note can be divided into quarter notes which can further be subdivided into eight notes and so on.
(c) <em>Meter</em>: A meter describes the structure of a beat. It is sometimes represented as the time signature of a song. It defines how many individual beats there would if one were clapping their hands to the beat of a song.
(d) <em>Accents</em>: Accents refer to the stress or emphasis laid on a chord or musical note. They are a large measuring factor in the articulation of a musical piece.
(e) <em>Syncopation</em>: In music, syncopation describes an element of surprise. It occurs when rhythmic patterns fall on weak beats (or weak parts of the beat) rather than on strong beats. These kind of rhythms are usually easy to sing but difficult to transcribe.
(f) <em>Tempo</em>: The tempo of a beat in music is typically the speed of the beat - how fast the beats are being played or sung. It is often measured in beats per minute (BPM). This means that tempo is the number of beats played per minute.
Answer:
The velocity is 
Explanation:
From the question we are told that
The electric field is 
The magnetic field is 
Generally the force experienced by the electron due to the magnetic field is
Generally the force experienced by the electron due to the electric field is
Since from the question the net force is zero then
=> 
Substituting values
The Ammeter shows: I = 15 A,
The circuit resistance is R = 0.2 Ohms.
By the Ohm`s Law:
R = V / I or:
V = I · R
V = 15 A · 0.2 Ohms
V = 3 V
Answer: C ) 3 V.
