Displacement = 20.2 m
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
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.

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) *
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.
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?
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

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?
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.

a student wishes to find the volume of a piece of wood of irregular shape. her experiment requires the use of a small brass object of mass 200g. a] calculate the volume of the brass object. the density of brass is 8.4g/cubic cm.
Answer:
Volume, [tex]V=23.8\ cm^3[/tex]
Explanation:
It is given that,
Mass of small object of brass, m = 200 g
The density of brass is 8.4 g/cm³
We need to find the volume of the brass object. Density is equal to mass of an object per unit its volume.
So,
[tex]d=\dfrac{m}{V}[/tex]
V is the volume of the brass object
[tex]V=\dfrac{m}{d}\\\\V=\dfrac{200\ g}{8.4\ g/cm^3}\\\\V=23.8\ cm^3[/tex]
So, the volume of the brass object is [tex]23.8\ cm^3[/tex].
The volume of the brass object is 23.81 cm³.
Density is the ratio of the mass of a body and its volume. The S.I unit is kg/m³
To calculate the volume of the brass, we make use of the formula below
D = m/V................. Equation 1
Where D = density of the brass object, m = mass of the brass object, V = volume of the brass object.
make V the subject of equation 1
V = m/D.............. Equation 2
From the question,
Given: m = 200 g, D = 8.4 g/cm³
Substitute these values into equation 2
V = 200/8.4
V = 23.81 cm³
Hence, The volume of the brass object is 23.81 cm³

Answer:
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.

A straight stream of protons passes a given point in space at a rate of 2.5 x 109 protons/s. What magnetic field do they produce 1.5 m from the beam
Answer:
B = 5.3x10⁻¹⁷ T
Explanation:
The magnetic field can be calculated as follows:
[tex]B = \frac{\mu_{0}I}{2\pi R}[/tex]
Where:
μ₀: is the magnetic permeability = 4πₓ10⁻⁷ H/m
I: is the current

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