A 1300 kg car traveling with a speed of 3.5 m/s executes a turn with a 8.5 m radius of curvature.

Y_Kistochka [10]

Answer:

1.4 m/s/s (2.s.f)

Explanation:

The formula for centripetal acceleration is:

$a=\frac{v^{2} }{r}$ , where v is velocity and r is the radius.

In the question we are given the information that the car has a mass of 1300kg, a velocity of 2.5m/s, and a turn radius of 8.5m which are all the values we need. Therefore we can simply substitute in the values to solve the question:

$a=\frac{3.5^{2} }{8.5} \\a=1.4$

Therefore the centripetal acceleration of the car is 1.4m/s/s. (2.s.f)

Hope this helped!

According to Newton's Second Law of Motion, an object will accelerate if you apply what kind of force? Question 1 options: Frict

Bumek [7]

An unbalanced force is required to accelerate an object according to Newton's Second Law of Motion.

<h3>What does Newton's Second Law of Motion state?</h3>

It states that the force applied to the object is equal to the product of mass and acceleration.

$F = ma$

An object will accelerate when the net force applied on the object is more than zero or unbalanced.

The acceleration is the change in the direction or speed of the object. To achieve acceleration the force must be greater in a direction.

When force is greater in one the object move in that direction which is known as acceleration.

Therefore, an unbalanced force is required to accelerate an object according to Newton's Second Law of Motion.

Which process generates energy in the Sun?1) nuclear fusion2) nuclear fission3) chain reaction4) transmutation

Ber [7]

1) nuclear fusion

During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. During this process, radiant energy is released.

A harmonic wave is traveling along a rope. It is observed that the oscillator that generates the wave completes 37.6 vibrations

tangare [24]

Answer:

$\lambda = 25.79\ cm$

Explanation:

given,

Wave vibrates = 37.6

time = 27.9 s

maximum distance travel = 450 cm

time = 11.3 s

wavelength = ?

frequency of wave

$f=\dfrac{37.6}{27.9}$

f = 1.35 Hz

Speed of wave

$v = \dfrac{450}{11.3}$

v = 39.82 cm/s

wavelength of wave

v = fλ

$\lambda =\dfrac{v}{f}$

$\lambda =\dfrac{34.82}{1.35}$

$\lambda = 25.79\ cm$

Hence, wavelength of the wave is equal to 25.79 cm.

Whenever possible, these types of power plants should be built because they generate virtually no pollution. (2 points)

geniusboy [140]

Wind farms, solar collectors, and nuclear power plants generate no pollution.

But wind farms make noise, wind and solar are both hazardous to birds, and there's no known means of disposing of nuclear plant waste that's completely safe.
