Answer:

An object (even if it is not living) will resist a change in its state, either resting or in motion, this is called <u><em>inertia</em></u>.

Explanation:

Newton's First Law states that "Every body perseveres in its state of rest or uniform rectilinear motion unless it is forced to change its state by forces printed on it." This means that for a body to leave its state of rest or uniform rectilinear motion, it is necessary for a force to act on it. For this reason Newton's First Law is known as the Law of Inertia. Inertia is the resistance that an object has to a change in its state of motion.

In other words, inertia is the ability of matter to maintain its state of rest or uniform rectilinear motion as long as there is no force acting on it. The inertia can be separated into several groups or types of inertia.  For example:

  • The inertia related to bodies in a state of rest is called static inertia.
  • The inertia related to the bodies that are in this state of motion is called dynamic inertia.

Finally, <u><em>an object (even if it is not living) will resist a change in its state, either resting or in motion, this is called inertia.</em></u>

A 35.0-kg child swings in a swing supported by two chains, each 3.02 m long. The tension in each chain at the lowest point is 41
n200080 [17]

Answer:

Explanation:

Total tension must support the weight of the child and provide the necessary centripetal force.

    2T = m(g + v²/R)

2(414) = 35.0(9.81 + v²/3.02)

  828 = 35.0(9.81 + v²/3.02)

23.65 = 9.81 + v²/3.02

13.847 = v²/3.02

 41.81 = v²

      v = 6.47 m/s

F = 2(414) = 828 N    (ignoring the weight of the chains and seat)

A fisherman noticed that a float makes 30 oscillations in 15 seconds. The distance between two consecutive crests is 2 m. What i
never [62]

Answer:

Period T = 0.5 s

Frequency F = 2 Hz

Wave speed V = 4 m/s

Explanation:

Given that the

Number of oscillations = 30

Time taken = 15 seconds

The distance between two consecutive crests is called wavelength

Wavelength = 2m

Period is the ratio of time and the number of oscillations

Period T = 15/30 = 0.5 seconds

Frequency F is the reciprocal of period. That is,

F = 1/T

F = 1/0.5 = 2Hz

Wave speed V is the product of frequency and wavelength

V = 2 × 2 = 4m/s

3. What are the two parts of a shadow?
Zielflug [23.3K]

Answer:

the umbra and penumbra

Explanation:

The two parts of a shadow are the umbra and penumbra.

A shadow is an expression formed when light from a source is cut blocked by an opaque body.

Most shadows are made up of two parts, umbra and penumbra.

  • The umbra is the darkest, and the innermost part of a shadow.
  • In the penumbra, only a portion of the light source is blocked. It is more of like a partial shadow.

The umbra is directly formed by light which impinges on an opaque body and it completely cut off.

2. A 1,100 kg car comes uniformly to a stop. If the vehicle is accelerating at -1.2 m/s ², which force is closest to the net for
Andrew [12]

Answer:

Since the car comes uniformly to a stop, the force that acts on the vehicle is the net force whose magnitude is equal to 1320 N.

Explanation:

The force acting on the vehicle is given:

F = ma

Where:

m: is the mass = 1100 kg

a: is the acceleration = -1.2 m/s²

We can find the magnitude of the net force:

F = ma = 1100 kg*1.2 m/s^{2} = 1320 N

Since the car comes uniformly to a stop, the force that acts on the vehicle is the net force calculated above.        

I hope it helps you!
