An aircraft jet engine has a thrust of I80N. What impulse is produced in 30 S?

neonofarm [45]

The impulse that was produced by this aircraft jet engine is 5,400 Ns.

Given the following data:

Thrust = 180 Newton.

Time = 30 seconds.

To determine the impulse that was produced by this aircraft jet engine:

<h3>How to calculate impulse.</h3>

Mathematically, impulse is given by this formula:

$I = Ft$

Where:

F is the force or thrust.

t is the time measured in seconds.

Substituting the given parameters into the formula, we have;

$I = 180 \times 30$

Impulse, I = 5,400 Ns.

the number of words Sylvia types varies directly with the amount of time she spends typing. If Sylvia types 100 words in 2.5 min

Eddi Din [679]

Answer:

600 words

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (100, 2.5, 5) as shown below:

$\frac{100}{2.5}=\frac{x}{15}$

Next we cross multiply. We multiply 2.5 and x, and we multiply 100 and 15.

$2.5(x)=2.5x$

$100(15)=1,500$

Now, lets put the values above back into the equation:

$2.5x=1,500$

Our next step is to divide 1,500 by 2.5 to get x by itself.

$x=\frac{1,500}{2.5}$

$x=600$

Sylvia can type 600 words in 15 minutes.

Aria walked down a trail into a valley. V(d) models Aria's vertical distance from the top of the valley (in kilometers) after wa

Snezhnost [94]

Answer: It means Aria's vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.

Step-by-step explanation:

Since, Here d represents distance along the trail.

And, V(d) represents the vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.

If the distance along the trial is 3 km.

That is, d = 3

Then the vertical distance she walked from the top of the valley = V(3)

But According to the question,

V(3) < 3

Her vertical distance from the top of the valley after walking 3 km along the trail is less than 3 km.

In other words, For going 3 km along the trail her vertical distance from the top of the valley is less than 3.

Which of the following expression would give a sequence with a first term of -4 and a common difference of 3

balandron [24]

Answer:

D) 3n-7

The $n^{th}$ of the given sequence $t_{n} = 3n -7$

Step-by-step explanation:

Explanation:-

Given that the first term a = -4

Given that the common difference 'd' = 3

The $n^{th}$ of the given sequence

$t_{n} = a+(n-1)d$

$t_{n} = -4+(n-1)3$

$t_{n} = -4 + 3n -3$

The $n^{th}$ of the given sequence $t_{n} = 3n -7$
