what is the relationship between a boats volume and the amount of mass it can hold before sinking
Answer:
Explanation:
the rilation shhip betveen boats annd volummes are ver expennsive
The buoyancy of a boat and the density of the materials used in its construction have an impact on the connection between its volume and the amount of mass it can support before sinking.
Thus, The buoyancy principle asserts that the upward force a fluid (in this case, water) exerts on a submerged or floating item is equal to the weight of the fluid displaced by the object, which is why a boat floats in water.
A boat moves as much water as its own volume while it is submerged in water.
A boat will float if its total weight, including its passengers and cargo, is less than the weight of the water it moves.
Thus, The buoyancy of a boat and the density of the materials used in its construction have an impact on the connection between its volume and the amount of mass it can support before sinking.

A child traveling 5 m/s on a sled passes her younger brother. If her average acceleration on the sledding hill is 2 m/s^2. how fast is she passes her older brother 4 s later?
Answer:
13 m/s
Explanation:
Given average acceleration a and initial velocity v0 we can compute the final velocity using the equation
a = (v - v0)/t where t is the time taken to reach final velocity from initial velocity
Here a = 2 m/s² and v0 is the initial velocity when she passes her younger brother v0 = 5m/s.
It takes t = 4 s to pass her older brother at which time her speed is v, say
Then
a = (v - v0)/t
Plugging in known values,
2 = (v - 5)/4
Switch sides:
(v- 5)/4 = 2
Multiply both sides by 4:
v - 5 = 8
v =5 + 8 = 13 m/s - the speed at which she passes her older brother
Which of the following will cause the decrease in an objects weight
When the mass of the object decreases the weight of the object will decrease.
Newton's universal law of gravitation states that the force of attraction between any two bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their masses.
We know that weight is the product of applied gravitational force and mass.
Therefore, W = M × G
Where W represents the weight of the object, M is the mass of the object, and G is the gravitational force. As a result, it might also mean that "an object's weight is directly proportionate to its mass."
Therefore, a decrease in mass will result in a decrease in the object's weight.

1 The ball travel 58.29 m high
2. The time the ball spend in the air is 8.67 s
1. How to determine the maximum heightThe maximum height reached by the ball can be obtained as follow:
Initial velocity (u) = 33.8 m/sFinal velocity (v) = 0 m/s (at maximum height) Acceleration due to gravity (g) = 9.8 m/s²Maximum height (h) =?v² = u² – 2gh (since the ball is going against gravity)
0² = 33.8² – (2 × 9.8 × h)
0 = 1142.44 – 19.6h
Collect like terms
0 – 1142.44 = –19.6h
–1142.44 = –19.6h
Divide both side by –19.6
h = –1142.44 / –19.6
h = 58.29 m
2. How to determine the time spend by the ball in the airWe'll begin by calculating the time to reach the maximum height . This can be obtained as follow:
Initial velocity (u) = 33.8 m/sFinal velocity (v) = 0 m/s (at maximum height) Acceleration due to gravity (g) = 9.8 m/s²Time to reach maximum height (t₁) =?v = u – gt (since the ball is going against gravity)
0 = 33.8 – (9.8 × t₁)
0 = 33.8 – 9.8t₁
Collect like terms
0 – 33.8 = –9.8t₁
–33.8 = –9.8t
Divide both side by –9.8
t₁ = –33.8 / –9.8
t₁ = 3.45 s
Next, we shall determine the time take to fall to the ground
Acceleration due to gravity (g) = 9.8 m/s²Maximum height from building = 58.29 mHeight of building = 75 mTotal height (h) = 58.29 + 75 = 133.29 mTime to fall to the ground (t₂) =?h = ½gt²
133.29 = ½ × 9.8 × t₂²
133.29 = 4.9 × t₂²
Divide both side by 4.9
t₂² = 133.29 / 4.9
Take the square root of both side
t₂ = √(133.29 / 4.9)
t₂ = 5.22 s
Finally, we shall determine the time spend by the ball in the air. This is shown below:
Time to reach maximum height (t₁) = 3.45 sTime to fall to the ground (t₂) = 5.22 sTotal time (T) = ?T = t₁ + t₂
T = 3.45 + 5.22

[tex]V(bar)=46.33(km/hr).[/tex]
Explanation:Let's refer to the formula of average velocity.
Formula: [tex]V(bar)=\frac{td}{ct}[/tex], where td is the todal displacement, and ct is the change in time.
Since we're trying to find out the average velocity of the whole event (from time 0 when the car started moving to time 30 minutes when it finished the trip), we must take 30 minutes as our change in time.
Now, we need to find the distance traveled by the car on each instance of speed:
1. Distance covered with speed 1.
To find the covered distance, use the following formula.
[tex]d=vt[/tex], where "v" is velocity, and "t" is time.
Note. When using this type of formulas, all variables must match units. For example, say that your velocty is on km/hr, this means that the time or distance you input or calculate is going to be on kilometers or hours.
Find the value.
[tex]d=(61(km/h))(10(min))\\ \\d=610 (km).[/tex]
2. Distance covered with speed 2.[tex]d=(39(km/h))(20(min))\\ \\d=780 (km).[/tex]
3. Find average velocity through the given formula.Note. We add up both calculated distances to find the total displacement of the car.
[tex]V(bar)=\frac{td}{ct}\\ \\V(bar)=\frac{610(km)+780(km)}{30(min)}\\ \\V(bar)=46.33(km/hr).[/tex]
The average velocity of the car in Km/h during the trip is 98.37 Km/h
What is velocity?Velocity is simply defined as the rate of change of displacement with time. Mathematically, it can be expressed as:
Velocity = displacement / time
What is average velocity?This is the total displacement travelled divided by the total time taken to cover the displacement. Mathematically, it can be expressed as:
Average velocity = Total displacement / total time
How to determine the displacement travelled in the first 10 minsVelocity = 61 Km/hTime = 10 mins = 10 / 60 = 0.167 h displacement =?Displacement = velocity × time
Displacement = 61 × 0.167
Displacement = 10.187 Km
How to determine the average velocity Total displacement = 10.187 + 39 = 49.187 KmTotal time = 10 + 20 = 30 mins = 30 / 60 = 0.5 hAverage velocity =?Average velocity = Total displacement / total time

The initial velocity of the keys is 13.17 m/s.
A student tosses her sorority sister, who is in a window 2.30 meters above, a set of keys vertically upward.
The second student catches the key 2.50s later.
We simulate the keys as a particle falling at a steady speed. Assume that the positions of the first and second students are, respectively, y(i) = 0 and y(f) = 2.30m.
Now, we have
The time of flight of the keys is t = 2.50 seconds.
Now, the acceleration is a(y) = -9.8 m/s²
We will use the equation of motion,
y(f) = y(i) + v(yi) × t + ( 1/2 ) × a(y) × t²
v(yi) = [ y(f) - y(i) - ( 1/2 ) × a(y) × t² ] / t
v(yi) = [ 2.3 - 0 - ( 1/2 ) × ( - 9.8 ) × (2.5)² ] / 2.50

The accelerating force of the wind on a small 200-kg sailboat is 707 N northeast. If the drag of the keel is 500 N acting west, what is the acceleration of the boat?
The acceleration of the boat is 2.5 m/s².
The weight of a small sailboat is 200 kg.
The accelerating force of the wind on the boat is 707 N northwest and 500 N acting west.
Taking into consideration the wind's accelerating force. It can be visualized as the combination of two elements:
707 /√2 = 500 N acting north, and
707 /√ 2 = 500 N acting east.
It is acting both to the North and to the East because it is supposed to be acting in the Northeast wards. The drag of the keel's eastward component will then cancel out its westward counterpart.
Essentially, 500 N north will then be the result of two forces acting on the boat.
Then, we divide the force by the specified mass in order to obtain the boat's acceleration.
500/200 = 2.5 m/s² northward.
