a 0.1 kg block attached to a spring of force constant 13.1 n/m oscillates with an amplitude of 11 cm. find the maximum speed of the block. answer in units of m/s

Answer:

0.4 hour or 24 minutes

Explanation:

Knowing the formula:

\( \displaystyle{ \vec v = \dfrac{ \vec s}{t}}\)

v is velocity, s is displacement and t is time. We know two values which are s = 108 km and v = 270 km/h. Substitute in the formula:

\( \displaystyle{ 270 \ \text{km/h} = \dfrac{108 \ \text{km}}{t}}\)

Solve for t:

\( \displaystyle{ 270 \ \text{km/h} \cdot t= 108 \ \text{km}} \\ \\ \displaystyle{t= \dfrac{108 \ \text{km}}{270 \ \text{km/h}}} \\ \\ \displaystyle{t= 0.4 \ \text{h}}\)

Therefore, it will take around 0.4 hour or converting to minutes. We know that 1 hour = 60 minutes. Multiplying 0.4 both sides, hence:

0.4 hour = 0.4 × 60 minutes = 24 minutes.

Linear mass density and tension are the two factors on which the speed of the transverse waves on a string depends.

The square root of the linear mass density determines the speed of a wave on a string, with larger speeds occurring when the linear mass density is lower.

The linear density divided by the square root of the tension determines the wave's speed on a taut string.

The qualities of the medium affect a wave's speed. For instance, the sound of a guitar is created by the vibration of the strings. The wavelength and wave speed on the strings influence the frequency of the sound that is produced. A guitar's strings can be composed of materials that are similar in composition but varied in thickness.

Answer:

what scenario i dont understand

Explanation:

step by step explenation

The vertical component of the tension is 1,177.05 N while the horizontal component of the tension is 127.47 × 3.90² = 1,949.04 N.

The magnitude of the centripetal acceleration is 2.14 m/s².

A) The vertical component of the tension equals the weight it supports, which is the weight of the person plus the weight of the basket:

Weight = (82.0 kg + 45.0 kg) × 9.81 m/s²

Weight = 1,177.05 N

Therefore, the vertical component of the tension is 1,177.05 N.

To find the horizontal component of the tension, we can use the fact that the net force in the horizontal direction is zero when the basket is moving at a constant speed.

The only horizontal force is the component of the tension perpendicular to the radius, so:

The horizontal component of tension = centripetal force

Horizontal component of tension = (mass × centripetal acceleration)

Horizontal component of tension = (82.0 kg + 45.0 kg) × (v²/7.10 m)

Horizontal component of tension = 127.47 v² N

Setting these two components equal to each other gives:

1,177.05 N = 127.47 v² N

Solving for v gives:

v = 3.90 m/s

Therefore, the horizontal component of the tension is 127.47 × 3.90² = 1,949.04 N.

B) The centripetal acceleration is given by:

a = v²/r

a = (3.90 m/s)²/7.10 m

a = 2.14 m/s²

Therefore, the magnitude of the centripetal acceleration is 2.14 m/s².

C) The speed of the basket and its passenger is 3.90 m/s.

D) The time it takes the basket to make one complete circle is given by:

T = 2πr/v

T = 2π(7.10 m)/3.90 m/s

T = 12.9 s

Therefore, it takes the basket 12.9 s to make one complete circle.

The focal length of the mirror will be 0.33 m

Focus is defined as the point through which the reflected light rays pass (or appear to pass) when incident light rays are parallel to the principal axis. It is located at the midpoint of pole and center of curvature. The distance between the pole and the focus of the mirror is called the focal length of the mirror.

F =2R or focal length of a mirror is half of its radius of curvature.

The radius of curvature of convex or concave mirror is equal to two times of the focal length of convex or concave mirror. The radius of curvature is the radius of sphere formed by the convex or concave mirror. It is also equal to the distance between the pole and center of curvature.

When you make a 50:50 mixture of benzoic acid and salicylic acid, the most likely outcome is a decrease in the melting point of the mixture. This is due to the phenomenon known as eutectic behavior.

Eutectic behavior occurs when two substances with different melting points are combined in certain proportions. In this case, benzoic acid has a higher melting point than salicylic acid. When they are mixed together in equal amounts, a eutectic mixture is formed.

The eutectic mixture has a lower melting point than either of the pure substances. This is because the two substances interact at the molecular level, disrupting the crystal lattice structure and making it easier for the mixture to melt.

By creating a 50:50 mixture of benzoic acid and salicylic acid, you are essentially creating a eutectic mixture, which will result in a decrease in the melting point. It's important to note that the extent of the decrease will depend on the specific properties of the two substances involved.

Explanation:

First, we needed to calculate the radius and this will be:

= 0.900km / 2

= 0.450km

Since s = 3.00miles, we need to convert it to kilometers and this will be:

1mile = 1.6km

3 miles = 3 × 1.6km = 4.8km

Radians = s/r = 4.8/0.45 = 10.67

Answer:

x = 45 [m]

Explanation:

To solve this problem we must use the following kinematics equation:

\(v_{f}^{2} = v_{i}^{2}-(2*a*x)\)

where:

Vf = final velocity = 0

Vi = initial velocity = 15 [m/s]

a = desacceleration = 2.5 [m/s^2]

x = distance [m]

Note: the negative sign in the equation above, is because the car slows down.

0^2 = 15^2 - (2*2.5*x)

2*2.5*x = 15^2

x = 45 [m]

To find the speed of nitrogen molecules in the air at the coldest temperature ever recorded in the US, which was -62.1°C (-78.9°F), we can use the formula for root-mean-square (rms) speed of gas molecules:

v_rms = sqrt(3 * R * T / M)

where:
- v_rms is the root-mean-square speed
- R is the universal gas constant (8.314 J/mol·K)
- T is the temperature in Kelvin (convert from Celsius)
- M is the molar mass of nitrogen gas (N₂, approximately 28.0134 g/mol, which needs to be converted to kg/mol)

Step 1: Convert the temperature to Kelvin
T = -62.1°C + 273.15 = 211.05 K

Step 2: Convert the molar mass of nitrogen to kg/mol
M = 28.0134 g/mol * (1 kg/1000 g) = 0.0280134 kg/mol

Step 3: Calculate the rms speed of nitrogen molecules
v_rms = sqrt(3 * 8.314 * 211.05 / 0.0280134) ≈ 509.65 m/s

So, the speed of nitrogen molecules in the air that day was approximately 509.65 m/s.

Polar jet streams are formed because of the warm and cold air masses.

Polar front jet stream, also called polar front jet or mid-latitude jet stream stream, a belt of powerful upper level winds that sits at top the polar front.

The winds are strongest in the troposphere, which is the upper boundary of the troposphere, and move in a generally westerly direction in mid-latitudes.

The vertical wind shear which extends below the core of this jet stream is associated with horizontal temperature gradients that extend to the surface. As a consequence, this jet manifests itself as a front that marks the division between colder air over a deep layer and warmer air over a deep layer.

Polar jet streams are formed due to warm and cold air masses.

the magnet is not moving relative to the wire so B

Explanation:

The magnet is not moving relative to the wire if, A permanent magnet is placed in a coil of wire, If there is no electric current in the wire so, option B is correct.

Electric current is a term used to describe how much electricity flows across a circuit and how it flows in an electronic circuit. Amperes are used to measure it (A). The more electricity flowing across the circuit, the higher the ampere value.

When current flows through a coil of wire, it transforms into an electromagnet. The coil spins as a result of the electromagnet's interaction with a permanent magnet.
