hi, your answers are correct

Explanation:

Answer:

Explanation:

Momentum

Answer:

There would be 600km

Explanation:

Answer:

Extension, e = 0.4 meters

Explanation:

Given the following data;

Force = 40N

Spring constant, k = 100N/m

To find the extension;

Force = spring constant * extension

Substituting into the equation, we have

40 = 100 * extension

Extension, e = 40/100

Extension, e = 0.4 meters

Therefore, the spring can be compressed by the force over a distance of 0.4 meters.

Answer:

[tex]v = 0.25m/s[/tex]

Explanation:

Given

[tex]\lambda = 0.02m[/tex] --- Wavelength

[tex]T = 8.0 * 10^{-2}s[/tex] --- Period

Required

Determine the velocity of the wave

This is calculated using:

[tex]v = \frac{\lambda}{T}[/tex]

[tex]v = \frac{0.02m}{8.0*10^{-2}s}[/tex]

[tex]v = \frac{0.02m}{8.0*0.01s}[/tex]

[tex]v = \frac{0.02m}{0.08s}[/tex]

[tex]v = 0.25m/s[/tex]

Hence, the velocity is 0.25m/s

Answer:

0.75m/s^2

Explanation:

3.6-1.2=2.4 m/s (Change in velocity)

2.4/3.2=0.75 m/s/s or m/s^2

Answer:

10 hours earlier than regular train

Explanation:

In this case you are already giving the expression to be used which is:

S = D/t   (1)

The problem is giving us the data of the speed of both trains, and we also know the distance between City A and B, which is 4000 km, therefore, we just need to solve for t in the above expression for both trains, and then, do the difference between their times and see how much earlier the express train arrives.

Solving for t, we have:

t = D/S   (2)

For Train 1 (The regular):

t₁ = 4000 / 80

t₁ = 50 h

For Train 2 (Express):

t₂ = 4000 / 100

t₂ = 40 h

Now, as expected express train arrives earlier, now let's see how much:

T = t₁ - t₂

T = 50 - 40

Therefore, Express train arrives 10 hours earlier than regular train.

Answer:heart

The hardest working muscle is the heart. It pumps out 2 ounces (71 grams) of blood at every heartbeat. Daily the heart pumps at least 2,500 gallons (9,450 liters) of blood. The heart has the ability to beat over 3 billion times in a person's life.

Answer:

a) 2000 m

b) 1500 mm

c) 580000 cm

d) 400 mm

e) 2.7 cm

f ) 0.126 m

g) 0.012 km

Explanation:

Transform

a) 2km to m

   1 km = 1000m

hence : 2 km = 2 * 1000 =  2000 m

b) 1.5m to  mm

    1 m = 1000 mm

hence: 1.5 m = 1.5 * 1000 = 1500 mm

C) 5.8 km  to cm

     1 km = 100000 cm

hence ;5.8 km = 5.8 * 100000 = 580000 cm

D) 0.4 m   to  mm

   1 m = 1000 mm

hence; 0.4 m =  0.4 * 1000 = 400 mm

E) 27 mm to  cm

   1 mm = 0.1 cm

hence ; 27 mm = 27 * 0.1  = 2.7 cm

F) 126mm  to m

    1 mm = 0.001 m

hence ;  126 mm = 126 * 0.001 = 0.126 m

G) 12m  to Km

   1 m = 0.001 km

hence ; 12 m = 12 * 0.001 = 0.012 km

Explanation:

Electrical energy is energy derived from electric potential energy or kinetic energy. When used loosely, electrical energy refers to energy that has been converted from electric potential energy.

Distance = (speed) x (time)

Time = (distance) / (speed)

Time = (22 km) / (55 km/hr)

Time = (22/55) (hr)

Time = 0.4 hour  (that's 24 minutes)

Answer:

carbon dioxide, water , salts , urea and uric acid.

Explanation:

These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion

Answer:

1.96m/s^2

Explanation:

According to Newtons second law;

F = ma

a = F/m

a = nR/m

a = nmg/m

a = ng

n is he coefficient of friction = 0.2

g  = 9.8m/s^2

a = 0.2 * 9.8

a = 1.96m/s^2

Hence the acceleration of the box is 1.96m/s^2

Answer:

391.67Hz

Explanation:

The fundamental frequency formula in string is expressed as;

Fo = V/2L

V is the velocity of the wave = 329m/s

L is the length of the string = 42cm = 0.42m

Substitute

Fo = 329/2(0.42)

Fo = 329/0.84

Fo = 391.67Hertz

Hence the  fundamental frequency of a mandolin string is 391.67Hz

Answer:

False.

Explanation:

Potential of Hydrogen is the full form of PH.

Potential of Hydrogen tells about the acidity or basicity of the solution.

The pH of a solution is a measure of the concentration of hydrogen ions [tex](H+)[/tex] ions and hydroxide ions [tex](OH-)[/tex] in a solution.

So, the given statement is false.

Answer:

F = 144 N

Explanation:

For this exercise we will use Neqwton's second law. Let's fix a reference system with the x-axis in the direction of the sled, let's write the forces for each part

Sack, let's use subscript 1

Y axis  

       N₁-W₁ = 0

       N₁ + W₁ = m₁ g

X axis

       fr₁ = m a₁

the expression for the friction force is

       fr = μ₁ N₁

we substitute

        μ₁ m₁ g = m a₁

Sled, subscript 2

Y axis

       N₂ - W₁ -W₂ = 0

       N₂ = W₁ + W₂

       N₂ = (m₁ + m₂) g

X axis

       F - fr₁ -fr₂ = m a₂

the expression for the deroce force is

      fr = μ N

we substitute

       F - μ₁ m₁g - μ₂ (m₁ + m₂) g = m a₂

as it indicates that the velocity is constant the acceleration of the sled is zero (a₂ = 0)

       F = μ₁  m₁g + μ₂  (m₁ + m₂) g

       F = g (m₁ (μ₁ + μ₂) + μ₂ m₂)

let's calculate

       F = 9.8 (50 (0.07 + 0.1) + 62 0.1)

       F = 144 N
