Answer:

X = 12N

Explanation:

Anticlockwise moment = Clockwise moment

Taking the moment at the pivot,

Anticlockwise moment = X×2.0m

Clockwise moment = (2.0N × 4.0m) + (4.0N × 4.0m)

Hence, 2X = (8 + 16)

2X = 24

X = 12N.

Sebuah vektor gaya sebesar 40 N membentuk sudut 30° terhadap sumbu x positif. Komponen-komponen vektor tersebut terhadap sumbu x dan sumbu y adalah … N (Sin 30°= 1/2 √3 ; Cos 30°= 1/2) *

Answers

Answer:

Explanation:

Given that the force 40N F acting on the Cartesian x and y coordinates and forming an angle of 30 ° to the positive x-axis, the vector of the force component about the horizontal and vertical axes will be expressed as shown;

For the component force x;

Fx = Fcostheta

You know that F = 40N and theta = 30 °

Fx = 40cos30 °

Fx = 40 * √3 / 2

Fx = 40√3 / 2

Fx = 20√3 N

For the component force y;

Fy = Fsintheta

You know that F = 40N and theta = 30 °

Fy = 40sin30 °

Fy = 40 * 1/2

Fy = 20 N

Therefore, the vector components with respect to the x-axis and the y-axis are 20√3 N and 20N, respectively.

A mouse ran 100 centimeters in
20 seconds. What was his speed?
A. 5 cm/s
B. 0.2 m/s
C. 2000 m/s
D. 120 m/s

Answers

Explanation:

Speed = 100/20 = 5cm/s

Option A is the correct answer

Speed = Distance/Time, therefore the speed of the mouse is 5 cm/s. Hence, option A is correct.

What is speed?

The pace at which a distance changes over time is referred to as speed. It has a dimension of time distance. As a result, the fundamental unit of time and the basic unit of distance are combined to form the SI unit of speed. Thus, the meter per second (m/s) is the SI unit of speed.

You can determine an object's speed if you know how far it moves in a given amount of time. For instance, an automobile is moving at a pace of 70 miles per hour if it covers 70 miles in an hour (miles per hour).

If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as speed = distance/time. Hence, option A is correct.

Explanation:

Given that Vanessa runs on the soccer field 20 meters North, then makes a cut to the right going East for 3 meters. What is Vanessa’s displacement from her original spot?

The Vanessa displacement can be calculated by using pythagorean theorem.

Displacement = sqrt( 20^2 + 3^2 )

Displacement = sqrt( 400 + 9 )

Displacement = sqrt( 409)

Displacement = 20.2 m

If someone told you that they traveled 50 km east, are they describing the distance they traveled or their displacement? How do you know? *

Answers

Answer:

They are describing their displacement

Explanation:

The correct answer would be that they are describing their displacement.

Distance is a scalar quantity while displacement is a vector quantity. A scalar quantity only has magnitude without any indication of the direction while a vector quantity has both magnitude and direction.

Hence, if someone travels 50 km east, the distance they covered is only 50 km while the displacement is 50 km in the eastward direction.

A newly discovered planet has a radius twice as large as earth's and a mass five times as large. What is the free-fall acceleration on its surface?

Answers

Answer:

free-fall acceleration = 12.25 m/s²

Explanation:

Formula for free fall acceleration is given by the gravity equation;

g = Gm/r²

Where;

M is mass of the Earth

r is radius of the Earth

G is the gravitational constant

Now, that equation applies to the earth.

For this new planet, we are told that the mass = 5 × mass of earth

And radius = 2 × radius of earth.

Thus, free fall acceleration for this planet is;

g_p = G(5m)/(2r)²

g_p = (5/4)(Gm/r²)

Gravitational constant has a value of 6.674 × 10^(−11) N.m²/kg²

Mass of the earth = 5.972 × 10^(24) kg

Radius of the earth = 6378 km = 6378000

Thus;

g_p = (5/4)(6.674 × 10^(−11) × 5.972 × 10^(24))/(6378000²) = 12.25 m/s²

Allison wants to calculate the denisty of a rock. To do this, what tools will she need to measure
the mass and volume of the rock?

Answers

Answer:

Explanation:

Allison can measure the mass of the rock by using a scale. An electronic beam balance will be able to give her the mass of the rock to a fairly accurate degree.

To go about measuring the volume of the rock, an indirect approach has to be adopted since the rock is not regular in shape.  Allison would have to adopt a principle that explains that the volume a solid body displaces when immersed in a pool of liquid, is directly equal to the volume of the solid itself.

This means that if the stone is placed in a beaker of water containing an already measured volume of water, the increase in the volume of the water when the stone is immersed is equivalent to the volume of the stone.

The female silk moth lays eggs. When the eggs hatch a tiny Caterpillar comes out, This is the Silkworm or Larva. The silkworm feeds on leaves and grass. When it is ready to enter the next stage in its lifecycle, it first weaves a net around itself. It then secrets a fibre made up of proteins which hardens on exposure to air. This is the Silk fibre. It covers itself completely with this fibre to form a cocoon at this stage the Larva is called Pupa. The Pupa grows and changes inside the cocoon. A few weeks later the cocoon opens and an adult moth come out.

The Silk yarn is obtained from the cocoon of the silkworm. The breeding and management of silkworms is known as Sericulture.

Raul started out on his bike thirty meters to the south of my position. Five
seconds later, he was twenty meters to the north. How fast is Raul biking. Write
an equation to find his displacement, x, from the time, t. If he keeps going at the
same rate, where will he be one minute (sixty seconds from) when he started?​

Answers

Answer:

Let's define the North as the positive y-axis.

At t = 0s (t is the variable of time) we know that Raul is 30m at the South, so in our system, the position of Raul at t = 0s is:

p(0s) = -30m

After 5 seconds, at the time t = 5s, we know that the position of Raul is 20m at the North, so now the position is:

p(5s) = 20m.

a) First, speed is calculated as distance over time, or:

S = ( p(5s) - p(0s))/5s = (20m - (-30m))/5s = 50m/5s = 10m/s.

b) The displacement is defined as the difference between the final position and the initial position:

Displacement = p(5s) - p(0s) = 20m - (-30m) = 50m.

Now, knowing the speed is 10m/s, we can write the movement equation as:

p(t) = 10m/s*t + p(0s) = 10m/s*t - 30m

So the displacement at a time t is:

D = p(t) - p0s = 10m/s*t - 30m - (-30m) = 10m/s*t

c) the position one minute after he started will be:

p(1min)

But we have our equation in seconds, so we write 1min = 60s

p(60s) = 10m/s*60s - 30m = 600m - 30m = 570m

If the ball is accelerating down through the air with no horizontal motion, the net forces acting on the ball must follow: C. The gravitational force is greater than the drag.

Explanation:

This is because the gravitational force is directed downward and the drag force opposes the direction of motion (therefore the drag force is directed upwards).  Since the ball is accelerating downwards, the gravitational force must be greater than the drag force in order to create this acceleration.

We know that the other options are incorrect because if the net force on the ball was directed upwards, the ball would be accelerating upwards.  If the net force on the ball was zero, the ball would not be accelerating at all.  If the drag was greater than the gravitational force, then the ball would be accelerating upwards as well.

Answers

Answer:

The frequencies of the first four harmonics are 248 Hz, 496 Hz, 744 Hz, and 992 Hz

Explanation:

Given;

fundamental frequency, f₀ = 248 Hz

Frequency of the nth harmonic = n x fundamental frequency

First harmonic, f₁ = 1 x f₀ = 248 Hz

Second harmonic;

2f₀ = 2 x 248 Hz = 496 Hz

Third harmonic

3f₀ = 3 x 248 Hz = 744 Hz

Fourth harmonic

4f₀ = 4 x 248 Hz = 992 Hz

Therefore, the frequencies of the first four harmonics are 248 Hz, 496 Hz, 744 Hz, and 992 Hz
