Dacia asks katarina to tell her What the values of the Y or that can make sin

1 answer:

5 0

Katarina is right. The explanation correct is because r is a distance and always positive, from she can see that when y is negative, sinθ is also negative.

<h3>What is the explanation for the above?</h3>

For every interval of odd multiple of π, to next even multiple of π, sinθ will be negative.

Mathematically,

Sin θ will be negative in

[(2n +1)π, (2n + 2)π]

Where, n is any integer (Positive or negative).

Hence, it is right to state that Katarina is right. The explanation correct is because r is a distance and always positive, from she can see that when y is negative, sinθ is also negative.

pashok25 [27]

Answer:

The options are not provided, so i will answer in a general way.

We know that:

The movement is along a straight horizontal surface, then we have one-dimensional motion.

The speed is 2m/s

We want a graph of position vs time.

Now, remember the relation:

Distance = Speed*Time

Then we can write the position as a function of time as:

P(t) = 2m/s*t + P0

Where t is our variable, that represents time in seconds, and P0 is the position at time t = 0seconds, we can assume that this is zero.

Then the equation is:

P(t) = 2m/s*t

And the graph is something like:

In a front-end collision, a 1500 kg car with shock-absorbing bumpers can withstand a maximumforce of 80 000 N before damage occu

Harrizon [31]

Answer:

The bumper will be able to move by 0.01155m.

Explanation:

The magnitude of deceleration of the car in the front end collision.

$a = \frac{F_m}{m} \\$

$a = \frac{80000}{1500} \\$

$a = 53.33$

This is the deceleration of the car that is generated to stop due to a front end collision.

4 km/h = 1.11 m/s

Now, the initial speed of the bumper in the relation of car, Vi = 0

Now, the initial speed of the bumper in the relation of car, Vf = 1.11 m/s

Use the below equation:

$s = \frac{(Intitial \ speed)^2 – (Final \ speed)^2}{2a} \\$

$s = \frac{(1.11)^2 – (0)}{2 \times 53.33} \\$

$s = 0.01155 \\$

Thus, the bumper can move relative to the car is 0.01155 m .

rosijanka [135]

<span><span>The answer is A.

</span><span>Chlorine is found in group7A of the periodic table. This means that when they are neutral, (electrons and protons are equal), they lack 1 electron to complete the octet or eight valence electrons to be stable. This will result in Chlorine having to gain an electron. Since it gained an electron, that means the electrons outnumber the protons by 1, which will result in a negative charge of -1. </span></span>
