on the water. 10N of weight is acting
DOWNWARDS on the water. What other
force must be acting to allow the duck to
float?
The other force that must be acting on the duck is upthrust of 10 N.
The given parameters;
weight of the rubber duck, W = 10 NWhen the weight of the object is equal to the upthrust, the apparent weight will be zero and the object will float in the liquid. This is known as principle of floatation.
Since the given weight of the rubber duck is 10 N, then the upthrust on the duck will be 10 N to enable the duck float on the water.
Thus, the other force acting on the duck is upthrust of 10 N.

What is the gravitational force acting on a 53 kg object standing on the surface of the Earth?
a) 5.3 N
b) 63N
c)48N
d) 530N
Answer:
D.
Explanation:
DId the test
The gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.
What is Weight ?
Weight is the force exerted by earth on a body on the surface of earth. Mathematically -
W = mg
Given is a 53 kg object standing on the surface of the Earth.
The gravitational force acting on the body will be same as it weight and will be directed towards the center of earth. Using the formula for weight -
W = mg = 53 x 10 = 530 N [taken g = 10 m/s²]
Therefore, the gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.

Which line on the graph represents the greatest positive acceleration?
D
A
B
C
Answer:
I think it's B, if that's wrong I apologize. You might want to do more research on it and find the correct answer if you can, if it's right then you could like my comment, so others know if not give it 1 star, keep it low lol.
Explanation:
The line that represents the greatest positive acceleration is A.
In a velocity-time graph, the slope of the line represents the acceleration. The greater the slope, the greater the acceleration. Line A has the steepest slope, so it represents the greatest positive acceleration.
Line B has a positive slope, but it is not as steep as line A. Line C has a negative slope, which means it represents negative acceleration, or deceleration. Line D is a horizontal line, which means it represents a constant velocity, or zero acceleration.
Therefore, the line that represents the greatest positive acceleration is A.

Why is air pressure lower on top of the airplane wing?
Answer:
Explanation:
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing.

A skateboarder flies horizontally off a cement planter. After a time of 3 seconds (Δt), he lands with a final velocity (v) of −4.5 m/s. Assuming the acceleration is -9.8 m/s² (a), we can calculate the initial velocity of the skateboarder (v₀) using the kinematic equation A.
[tex]v = v_o + a \Delta t\\\\v_o = v - a \Delta t = (-4.5 m/s) - (-9.8 m/s^{2} ) \times 3 s = 24.9 m/s[/tex]

Answer:
Let y equal lambda the wavelength of the light

A treasure map directs you to start at palm tree
and walk due north for 15.0 m. You are then to turn
90° and walk 22.0 m; then turn 90° again and
walk 5.00 m.
Give the distance from the palm tree,and the direction to north, for each of the four possible locations of the treasure .
The direction of the 90° turns are the possible directions used for the calculations
The four distances and directions are;
24.2 m, 65.6° West of North29.7 m, 42.7° East of North24.2 m, 65.6° East of North29.7m, 47.7° West of NorthReason:
Let point A represent the motion of the treasure hunter, we have:
Turning West then West;
Walking due north to location (0, 15)
Turn 90° West and walk 22.0 m to the location (-22, 15)
Turn 90° West again and walk 5.00 m. to the location (-22, 10)
The location of point A = (-22, 10)
[tex]Direction \ of \ point \ A = arctan \left(\dfrac{10}{-22} \right) \approx -24.4^{\circ}[/tex]
Direction to North = 90° - 24.4° ≈ 65.6°
Distance = √((-22)² + 10²) ≈ 24.2
Therefore, we have;
24.2 m, 65.6° West of NorthTurning East then West:
Turn 90° East and walk 22.0 m to the location (22, 15)
Turn 90° West again and walk 5.00 m. to the location (22, 20)
The location of point A = (22, 20)
[tex]Direction \ of \ point \ A = arctan \left(\dfrac{20}{22} \right) \approx 42.7^{\circ}[/tex]
Direction to North = 90° - 42.3° ≈ 47.7° East
Distance = √((-22)² + 20²) ≈ 29.7
