Answer: trial 3
Explanation:
impulse equals force x time so for each trial it would be a force which is 500 x 8 individual time trial 3 has the highest time which would equal the highest impulse.
500 x .45 = 225
Answer:
14.7 m/s
Explanation:
Since the motion of the ball is a uniformly accelerated motion, we can find the initial speed by using the following suvat equation:
where
s is the vertical displacement
u is the initial velocity
t is the time
a is the acceleration
In this problem, we have:
s = 0 (because at the end of the motion, the ball returns to its original position)
u = ?
is the acceleration of gravity (negative because it is downward)
is the total time of flight
Solving for u, we find the initial velocity of the ball:
Answer:
Both use everyday language.
Explanation:
Language is the system through which man or animals communicate their ideas and feelings, either through speech, writing or other conventional signs, being able to use all the senses to communicate.
The term language is of Latin lingua origin.
The human being uses a complex language that expresses with sound sequences and graphic signs. Animals, meanwhile, communicate through sound and body signs, which even man has not been able to decipher, and which in many cases are far from simple.
Depending on the social context in which the language is produced, the speaker can use the formal language or technical language that is produced in situations that require the use of the standard language, for example, in classrooms or work meetings or language informal or everyday language that is used when there is intimacy between speakers, using colloquial expressions.
Everyday language is the use of informal, familiar language and is characterized by being a spontaneous, relaxed and expressive language. In everyday language, the speaker uses onomatopoeia, short sentences, repetitions, redundancies, among others. In turn, technical language is used by scientific and professional people.
We can calculate the length of each spring by using the relationship:
where
F is the force applied to the spring
k is the spring constant
x is the length of the spring (measured with respect to its rest position)
Re-arranging the equation, we have
The force applied to both spring is F=60 N. Spring A has spring constant of k=4 N/m, therefore its length with respect to its rest position is
Spring B has spring constant of k=5 N/m, so its length with respect to its rest position is
Therefore, the correct answer is
<span>
D.Spring A is 3 m longer than spring B because 15 – 12 = 3.</span>
To find the answer, plot down the factors for every number.
12: 1, 2 ,3 ,4, 6, 12
18: 1, 2, 3, 6, 9, 18
84: 1, 2, 3, 4, 6, 7, 12
If you noticed, the number that was common to the 3 numbers, were 1, 2, 3, and 6
And 6 is the bigger number
So 6 is your GCF
