Answer:

the motion of a car is negative

Explanation:

Answer:

Now, we know that velocity is maximum when y=0, i.e., displacement is zero and acceleration is zero, which means the system is in equilibrium. Therefore, at a point in simple harmonic motion, the maximum velocity can be calculated using the formula v=Aω.

Explanation:

Answer: 30 m/s

hope this helps

Assuming constant acceleration, we have

a (average) = a = ∆v/∆t

So if v is the rocket's velocity just before the second stage, we have

80 m/s² = (3600 m/s - v)/(25 s)

===> v = 3600 m/s - (80 m/s²) (25 s) = 1600 m/s

Answer:

0.25 m/s²

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

[tex]a = \frac{f}{m} \\ [/tex]

f is the force

m is the mass

From the question we have

[tex]a = \frac{475}{1900} = 0.25 \\ [/tex]

We have the final answer as

0.25 m/s²

The shortest length among the options is 3 nanometers (option three).

What is length?

Length is the distance measured along the longest dimension of an object.

The basic unit of length in the International System of Unit is metres.

According to this question, four units of lengths were given as follows:

2 millimeters3 nanometers1 micrometers4 centimeters

The equivalence of each measurement to metres is as follows:

2 millimeters = 2 × 10-³ m3 nanometers = 3 × 10-⁹ m1 micrometers = 1 × 10-⁶ m4 centimeters = 4 × 10-² m

Therefore, the shortest length among the options is 3 nanometers.

Answer:

The statement of the student is correct.

Since B attained a higher velocity in a short amount of time, that is it accelerated faster(having a larger slope).

Slope = dy/dx

That is, Velocity

Time

which is acceleration.

That's my guess.

Hope it's right.

C. 17 km

D. 500,000 g

A. 95/100

B. 1.1 x 1,000

C. 17,000/1,000

D. 500 x 1,000

given :

h = 97.0 m

g = 10.0m/s²

find:

a) t

b) Vt

solutions:

a)

h = ½.g.t²

97 = ½. 10.t²

97 = 5.t²

t² = 97/5 = 19.4

t =√19.4 = 4.4

the ball will remain in the air

for 4.4 s

b)

Vt = g. t

= 10 × 4,4

= 44 m/s

the balls speed before striking the ground

= 44 m/s

The ball remained in the air for approximately 4.41 seconds.

The ball's speed just before striking the ground was approximately 44.1 m/s.

Calculate the time it takes for the ball to reach the ground using the equation for motion with uniform acceleration:

[tex]s = ut + 0.5 * a * t^2[/tex]

where:

s is the distance (height) = 97.0 m

u is the initial velocity = 0 m/s (since the ball is dropped)

a is the acceleration = 10.0 [tex]m/s^{2}[/tex]

t is the time we're solving for

Plugging in the values, we get:

97.0 = [tex]0.5 * 10.0 * t^2[/tex]

Solving for t:

[tex]t^2[/tex] = 97.0 / 5.0

t = [tex]\sqrt{(97.0 / 5.0)[/tex]

t ≈ 4.41 seconds

Calculate the final velocity of the ball just before it strikes the ground using the equation:

v = u + at

where:

v is the final velocity

u is the initial velocity = 0 m/s

a is the acceleration = [tex]10.0 m/s^{2}[/tex]

t is the time = 4.41 seconds (calculated in the previous step)

Plugging in the values:

v = 0 + 10.0 * 4.41

v = 44.1 m/s

When a β− and a β+ particle meet and interact they are annihilated.

Every matter has an antimatter. An antimatter of a particular particle is another particle that has exactly the same properties as the initial particle but carries an opposite charge.

If we look at β− and β+ particles, we will notice that they are matter and antimatter. The interaction of matter and antimatter leads to annihilation. The energy produced by annihilation of matter and antimatter is enough to destroy the tissue.

So, when β− and a β+ particle meet and interact they are annihilated.

The position of the final image relative to the diverging lens to 1 decimal place to 35.4 cm to the left side of the diverging lens.

A converging lens is a lens that puts together rays of light that pass through its primary axis.

A diverging lens is a lens that causes light rays to spread out after they pass through the optical axis of the lens.

By using the Lens Formula from the information given:

[tex]\dfrac{1}{f}= \dfrac{1}{v}+\dfrac{1}{u}[/tex]

[tex]-\dfrac{1}{25}= \dfrac{1}{v}+\dfrac{1}{50}[/tex]

[tex]-\dfrac{1}{v}= \dfrac{1}{25}+\dfrac{1}{50}[/tex]

[tex]-\dfrac{1}{v}= \dfrac{3}{50}[/tex]

v = 16.67 cm

However, the above image distance relates to the object of the diverging lens.

The object distance can now be expressed as;

u' = (20 + 16.67) cm

u' = 36.67 cm

Again for a diverging lens according to the lens formula;

The final image distance formed is:

[tex]\dfrac{1}{18} = \dfrac{1}{v'}+\dfrac{1}{36.67}[/tex]

[tex]\dfrac{1}{v'}= \dfrac{1}{18} -\dfrac{1}{36.67}[/tex]

[tex]\dfrac{1}{v'}= \dfrac{1867}{6600}[/tex]

[tex]v' = \dfrac{66006}{1867}[/tex]

v' = 35.4 cm

Therefore, we can conclude that the object is placed at a distance of 35.4 cm to the left of the diverging lens

With the addition of vectors we can find that the correct answer is:

C) Q> P > R = S > T

The addition of vectors must be done taking into account that they have modulus and direction. The analytical method is one of the easiest methods, the method to do it is:

Set a Cartesian coordinate systemDecompose vectors into their components in a Cartesian systemPerform the algebraic sums on each axisFind the resultant vector using the Pythagoras' Theorem to find the modulus and trigonometry to find the direction.

In this exercise indicate that the modulus of all vectors is the same, suppose that the value of the modulus is A.

We fix a Cartesian coordinate system with the horizontal x axis and the vertical y axis, we can see that we do not need to perform any decomposition, so we perform the algebraic sums

In exothermic reactions, heat and light are released to the surrounding environment. On the other hand, in an endothermic reaction, heat is required and therefore it can be considered as a reactant.

In exothermic reactions, light and heat are released into the environment (Option D).

Exothermic reactions release energy in the form of heat or light.

Combustion reactions are generally exothermic reactions.

After an exothermic reaction takes place it is possible to observe that the energy of the products of the reaction is lesser than the energy of the reactants.

The energy released in exothermic reactions is evidenced by the increase in temperature of the reaction.
