In which situation are waves transmitted?

Answer:

The correct answer is - option C. G.

Explanation:

In this reaction diagram, there is a representation of the reaction profile. The reaction profile shows the change that takes place during a reaction in the energy of reactants or substrate and products. In this profile, activation energy looks like a hump in the line, and the minimum energy required to initiate the reaction.

The overall energy of the reaction, including or excluding activation energy depends on the nature of the reaction if it is exothermic or endothermic. and products are represented by the G which shows the difference between the energy of the reactants and products.

The mass of the basswood wing with the given dimension is 710.14 g.  Basswood is a low-density, light wood.

Basswood is a low-density, light wood that is mainly used for artistic work such as hand carving and creating musical instruments.

The mass can be calculated by the formula,

[tex]m = v \times d[/tex]

Where,

[tex]m[/tex]- mass

[tex]v[/tex] - volume = 26.9 cm x 5.5 cm x 0.15 cm =  22.192 ml

[tex]d[/tex] - density = 32 g/cm3

Put the values in the formula,

[tex]m[/tex] = 22.192  x 32

[tex]m[/tex] = 710.14 g

Therefore, the mass of the basswood wing with the given dimension is 710.14 g.

Answer:

3.3kg

Explanation:

Given parameters:

Spring constant = 400N/m

Extension  = 8cm  = 0.08m

Unknown:

Amount of mass the spring is supporting  = ?

Solution:

To solve this problem:

     F  = kE

F is the force

k is the spring constant

E is the extension

  So;

            F  = 400 x 0.08  = 32N

Mass;

       Force  = mass x acceleration due to gravity

          32  = mass x 9.8

  Mass = 3.3kg

The mass the spring is supporting is 3.27 Kg.

We'll begin by calculating the force acting on the spring.

F = Ke

F = 400 × 0.08

F = 32 N

Finally, we shall determine the mass. This can be obtained as follow:

m = F / g

m = 32 / 9.8

m = 3.27 Kg

Therefore, the mass the spring is supporting is 3.27 Kg

Answer:

accelerated down the ramp

Explanation:

It can be concluded that the cart accelerated down the ramp is the correct choice.

Acceleration is the rate of change of velocity with time.

We see that as time increases, the velocity of the car also increase.

 Initially, the car is at rest with a velocity of 0cm/s. With the passage of time, as it slides down the ramp, the velocity increases to 25cm/s.

Since acceleration is the rate of change of velocity with time, it is glaring that the acceleration of the body greatly increased as it moves down the ramp

We need to calculate the time it had travelled first:

9:00 to 12:00 = 3 hours.

12:00 to 2:00 = 2 hours

Total travel time = 5 hours.

The formula for speed is distance ÷ time (Hence, the unit for speed is m/s, kph, mph, etc.)

= 629km ÷ 5 hours

= 125.8 km/hour ~ 125.8kph

Answer:

Explanation:

Given that,

Force, F = 35 N

It makes 10 degree angle with the positive x-axis.

We need to find the magnitude of the vertical component of the force. It can be given by :

[tex]F_y=F\sin\theta\\\\=35\times \sin(10)\\\\=6.07\ N[/tex]

So, the magnitude of the vertical component of the force is 6.07 N.

Answer:

Explanation:

The magnitude of the vertical component on any force when α is the angle between the direction of force and the X -axis is

[tex]F_y = F * Sin\alpha[/tex]

Explanation:

Answer:

The acceleration of the box is 2.05 m/s²

Explanation:

The given parameters of the motion of the box are;

The mass of the box, m = 50 kg

The pulling force, [tex]F_p[/tex] acting on the box = 200 N

The angle at which the force acts, θ = 30° above the horizontal

The coefficient of kinetic friction, [tex]\mu_k[/tex] = 0.25

The normal reaction from the box resting on a flat surface, N = The weight of the box, W - The vertical component of the pulling force, [tex]F_{py}[/tex]

N = W -  [tex]F_{py}[/tex] = m·g - [tex]F_p[/tex] × sin(θ)

Where;

g = The acceleration due to gravity = 9.8 m/s²

∴ N = W  - [tex]F_{py}[/tex] = m·g - [tex]F_p[/tex] × sin(θ) = 50 kg × 9.8 m/s² - 200 N × sin(30°)

∴ N = 490 N - 200 N × 0.5 = 390 N

The normal reaction, N = 390 N

The force of friction, [tex]F_f[/tex] = The coefficient of kinetic friction, [tex]\mu_k[/tex] × The normal reaction, N

∴ [tex]F_f[/tex] = [tex]\mu_k[/tex] × N = 0.25 × 390 N = 97.5 N

The net force, [tex]F_{NET}[/tex], acting on the block = The pulling force, [tex]F_p[/tex] - The friction force, [tex]F_f[/tex]

∴  [tex]F_{NET}[/tex] = [tex]F_p[/tex] - [tex]F_f[/tex] = 200 N - 97.5 N = 102.5 N

[tex]F_{NET}[/tex] = 102.5 N

According to Newton's second law of motion on the net force acting on an object, we have;

[tex]F_{NET}[/tex] = m × a

Where;

a = The acceleration of the box

∴ a = [tex]F_{NET}[/tex]/m = 102.5 N/(50 kg) = 2.05 m/s²

The acceleration of the box = a = 2.05 m/s².

Answer:

Hypothesis is simply a theory given on something which may be correct or not.

Answer:

Explanation:

Answer:

17.6 m/s²

Explanation:

Given:

[tex]v_{f}[/tex] = 90 m/s (final velocity)

[tex]v_{i}[/tex] = 2 m/s (initial velocity)

Δt = 5s (change in time)

The formula for acceleration is:

[tex]a_{avg}[/tex] = Δv / Δt

We can find Δv by doing

Δv = [tex]v_{f}[/tex] - [tex]v_{i}[/tex]

Replace the values

Δv = 90m/s - 2m/s

Δv= 88m/s

Using the equation from earlier, we can find the acceleration by dividing the average velocity by time.

[tex]a_{avg}[/tex] = Δv / Δt

[tex]a_{avg}[/tex] = [tex]\frac{88m/s}{5/s}[/tex]

acceleration = 17.6 [tex]m/s^{2}[/tex]

We are given:

Radius of Venus=  6 * 10⁶ m

Height above the planet's ground = 9.4 * 10⁶ m

Mass of Venus = 4.867 * 10²⁴ kg

Finding the Gravitational Field:

We first need to calculate the distance between the center of masses

Distance between center of masses:

Since the point is above the surface of Venus, the radius of Venus and the height will add

Distance between the center of masses = 9.4*10⁶ + 6 * 10⁶

Distance (r) = 15.4 * 10⁶ m

Now back to Gravitational field!

We know the formula for Gravitational Field:

g = GM / r² [where g is the gravitational field, M is the mass of the planet, r is the distance between the center of masses and G is the gravitational constant]

plugging the known values in the formula:

g = (6.67 * 10⁻¹¹ * 4.867 * 10²⁴) / (15.4*10⁶)²       [G = 6.67*10⁻¹¹ Nm²/kg²]

g = (32.46 * 10¹³) / (237 * 10¹²)

g = (32.46 * 10¹³) / (23.7 * 10¹³)

g = 32.46/23.7                                                   [the 10¹³ got cancelled out]

g = 1.367 N/kg² (or m/s²)

The angle (to the horizontal) at which the slingshot is fired makes, θ = 55°

The path of the slingshot which hits the stationary balloon at the top of its flight = Parabolic trajectory

The horizontal component of the velocity = vₓ = v·cos(θ) = Constant

vₓ = 100 × cos(55°) ≈ 57.358

The horizontal speed with which the slingshot hits the balloon = vₓ ≈ 57.358 m/s.
