Answer:
true
Explanation:
On Earth, a scale shows that you weigh 585 N. What would the scale read on the Moon (g = 1.60 m/s2)? N
Answer:
95.51 N
Explanation:
First, find the mass in kg:
Fg = 585 N
Fg = m*g
585 N = m*9.8 m/s^2
m = 59.69 kg
Then, to find your weight (Fg) on the moon, you use the same equation of
Fg(moon) = m*g, except this time g = 1.60 m/s^2
Fg(moon) = 59.69 kg * 1.60 m/s^2
Fg(moon) = 95.51 N

10 A ship is made of 4000 m' steel of density
7900 kgm^3
a. What volume of fresh water
1000 kg m) would the ship need to
displace in order for it to float?
b. Explain how the design of the ship enables
it to displace this much water.
Answer:
Explanation:
mass of ship = volume x density
= 4000 x 7900 = 316 x 10⁵ kg
The ship must displace water equal to weight of ship that is 316 x 10⁵ kg .
If volume of displaced water be V .
V x 10³ is mass of displaced water
V x 10³ = 316 x 10⁵
V = 31600 m³.
b ) Now the volume of steel making ship is only 4000 m³ so if it is in the form of a lump , it will displace only water equal to its volume ie 4000 m³ . So in order that it may displace water equal to volume 31600 m³ , it must be given shape so that it is hollow .
A hiker has determined which hiking path to take through a national forest (A is the starting point and B is the final destination). Below is the map of that trail. What does the red line most likely represent?
Total displacement from A to B
Total distance of the path from A to B
Both Total displacement and distance of path from A to B
The shortest path between A and B
In the following equation, Vi represents initial velocity and Vf represents final velocity. The equation for average acceleration is a = (Vf - Vi)/t. Solve this formula for t.
t = a/(Vf - Vi)
t = (Vf - Vi)/a
t = a(Vf - Vi)
t = (Vf - Vi)a
Select the 2 equations that show the same correct relationship between Average Velocity, Distance, and Time.
d = vt
t = v/d
v = t/d
v = d/t

Use the information and diagram to answer the following question.
A Physics student builds a circuit as shown with the help of a battery, wires, switch and 2 light bulbs as shown.
Which of the following circuit elements should the student use to cause the bulbs to dim but not go out?
Answer:b
Explanation:
Because I don’t know
The circuit elements should be placed according to the diagram given in option B to cause the bulbs to dim but not to go out. Thus, the correct option is B.
What are the elements of an electric circuit?An electric circuit is the continuous closed path along which the electric current flows from the positive terminal of the circuit to the negative terminal of the battery. An electric circuit can be constructed easily by joining all the elements of the circuit together in order.
The components of an electric circuit are:
A cell or a battery, which is the source of electricity.
The connecting wires which act as conductor to flow electric current.
A key or a switch to control the current through the circuit.
A bulb or electric device which act as a load to the circuit.
The length of the electric wire increases the resistance through the circuit and decreases the current flowing through the circuit which in turn dims the bulb.
Therefore, the correct option is B.

A boy moves around a square path of side 15m. He completes 1 round in 40 sec. 1 Calculate the displacement of the boy at the end of 2min 20sec.
Plsss answer fast!
Answer:
Explanation:
2 min 20 sec = 140 sec .
In 40 sec one round
In 140 sec 140 / 40 round = 3.5 round .
That means the boy will be positioned at the diametrically opposite corner of the square path .
side of square path = 15 m
length of diameter = 15√2
= 21.21 m
Displacement of boy is 21.21 m .

Pred p = mxv> (1 kg) x (+5) = +5 kg m/s
Pblue: P = mxv
(1 kg) x (0) = 0 kg m/s
Answer:
Momentum of red car = 5kgm/s
Momentum of blue car = 0kgm/s
Explanation:
Momentum = mass × velocity
For the red car
Mass = 1kg
Velocity = 5m/s
Momentum of the red car = 1kg × 5m/s
Momentum of the red car = 5kgm/s
For the blue car.
Mass = 1kg
Velocity = 0m/s(shows that the blue car is stationery)
Momentum = 1kg ×0m/s
Momentum of the blue car = 0kgm/s

show that for a clósed organ pipe only odd harmonics are present wheras for an open organ pipe all the harmonics are present
Answer:
For a closed organ pipe, the point at the closed end is always a node, 'N' while the open end is always an antinode, 'A'
Therefore, for a closed organ pipe, we only have;
NA = N↔A = First harmonics = f₁
NANA = NA↔AN↔ NA = Third harmonics, = f₃ = 3·f₁
NANANA = NA↔AN ↔ NA ↔ AN ↔ NA = f₅ = 5·f₁
It can also be shown that for a closed organ pipe, only f₇, f₉, f₁₁, ... are present
Therefore, a closed organ pipe has only odd harmonics present
For an open organ pipe, we have;
ANA = First harmonics = f₁
ANANA = ANA ↔ ANA = Second harmonics = f₂ = 2·f₁
ANANANA = ANA ↔ ANA ↔ ANA = Third harmonics = f₃ = 3·f₁
Similar relationship exist for f₄, f₅, f₆...
Therefore, for an open organ pipe, all harmonics, (multiples of the fundamental, f₁) are present

A baseball player slows down as he slides to base is he balanced or unbalanced?
Answer : this pretty much gives you the answer Lol
Explanation:
Fundamentals. When the forces acting upon an object are balanced, the object will maintain its state of motion; that is, its velocity remains constant. If the forces are unbalanced, the object will either speed up or SLOW DOWN. ... And if an object is speeding up or slowing down, the forces are unbalanced.

An astronaut has a mass of 70kg.
The force of gravity on the Moon is approximately 1.5N/kg.
Calculate the weight of the astronaut when they are on the Moon.
Weight = .............................................................. N
Answer:
Weight = 105 Newton
Explanation:
Given the following data;
Mass = 70kg
Force of gravity = 1.5N/kg
To find the weight;
Weight = mass * force of gravity
Substituting into the equation, we have;
Weight = 70 * 1.5
Weight = 105 Newton
Therefore, the weight of the astronaut when they are on the Moon is 105 Newton.
