Why do oil tankers sit lower in water

Answers

Answer 1

When a lower tank is damaged, the incoming sea water pushes the oil in the damaged tank up into the ballast tank. Because of the hydrostatic pressure, there is an automatic transfer out of the damaged tank. The double-hull design is aimed at the probability of zero outflow.

Suppose y = 2x + 10. Find y if x = -2

Answers

Answer:

y = 6

Explanation:

Given parameters:

        Given equation:

                     y = 2x + 10

And supposing; x = -2

Unknown:

y = ?

Solution:

 We are going to solve this problem by substitution;

           y = 2x + 10

  since x = -2; input this into the equation to solve for y;

           y  = 2(-2) + 10 = -4 + 10  = 6

The value of y = 6

velocity is derived physical quantity why​

Answers

Answer:

Velocity is “how much distance you cover in a particular time.” Space and time are fundamental quantities, and meters and seconds are their base units. Velocity is a combination of a space and a time, and therefore its units — “m/s” – are “derived” from the units for space and time

Explanation:

An object on another planet with g = 25 m/s^2 hits the ground from rest in 4 seconds. How far did it fall?

Choices:
•200.0m
•100.0m
•1000.0m
•25.0m

Answers

Using the kinematics equations Vf=Vi+ (a)(t) and d=Vi(t)+1/2(a)(t)^2
and given:

d=?
Vi= 0 m/s
Vf=?
g= 25m/s^2 (so a= 25m/s^2)
t= 4sec

you first have to use Vf=Vi+ (a)(t) to solve for Vf:


Vf= (0m/s) + (25m/s^2)(4 sec)
Vf= 100m/s

Now using d=Vi(t)+1/2(a)(t)^2

d= 0m/s +1/2(25m/s^2)(4)^2

Which gives us d= 200.0 meters

в горизонтальном положении бревно длиной 18 м можно уравновесить на подставке, отстоящей на 3 м от его толстого конца. Если же подставка находится в 6 м от толстого конца, и на тонкий конец сядет рабочий массой 60 кг, то бревно снова будет в равновесии. Определите массу бревна.

Answers

Ответ:

90кг

Пояснение:

Найдите эскиз прилагаемой схемы. Масса бревна M размещается на отметке 3 см от толстого конца, а стержень размещается на отметке 6 см от массы бревна.

Согласно принципу момента, сумма момента по часовой стрелке равна сумме момента против часовой стрелки.

Вес корпуса в более тонкой части W = мг

W = 60 × 10 = 600 Н

Момент по часовой стрелке = 600 × 9

CW момент = 5400 Нм

Момент против часовой стрелки = M × 6

Момент ACW = 6M

Уравнять оба момента

6M = 5400

М = 5400/6

М = 900Н

Масса бревна = 900/10

Масса бревна = 90кг

An apple is dropped from a 260m high building. How long will it take to hit the ground in
seconds)?

Answers

Answer:

7.28 s

Explanation:

s=-260

u=0

assume a=-9.81

t=?

s=1/2at^2 + ut

-260=1/2 (-9.81) t^2 +0t

t=7.28 s

The time taken for the apple to hit the ground from the high building is 7.28s.

Given the data in the question;

Before the apple was dropped, it was initially at rest, so

Initial velocity; [tex]u = 0 m/s[/tex]Distance or height from which it was dropped from; [tex]s = 260m[/tex]

 

To find the time it will take for the apple to hit the ground

We use the Second Equation of Motion:

[tex]s = u^2 + \frac{1}{2}at^2[/tex]

Where s is the distance or height from which it was dropped, u is its initial velocity, t is time and a is the acceleration due to gravity.

We know that earth's gravitational field or acceleration due to gravity; [tex]g = 9.8m/s^2[/tex]

Since the apple is falling, it under gravity; [tex]a = g = 9.8m/s^2[/tex]

We substitute our values into the equation and find t

[tex]260m = (0m/s)^2 + (\frac{1}{2} \ *\ 9.8m/s^2\ *\ t^2 )\\\\260m = 4.9m/s^2 \ * \ t^2\\\\t^2 = \frac{260m}{4.9m/s^2}\\\\t^2 = 53.06^2\\\\t = \sqrt{53.06s^2} \\\\t = 7.28s[/tex]

Therefore, the time taken for the apple to hit the ground from the high building is 7.28s

What is acceleration?

The acceleration of an object is the rate of change of velocity with time. It is measured in meter per second square.

Velocity of the car

The car undergoes velocity when there is change in direction of the speed.

Can an object have a positive position, but a negative velocity? Explain your reasoning.

Answers

Answer:

Yes

Explanation:

A position describes the position of an object relative to the x/y-axis (or the four cardinal directions). A velocity is a vector quantity, defining speed with direction.

So if an object is in a positive position, it means they are in the positive x-axis direction (or wherever on the scale the positive values are stated to be) and if it has a negative velocity, it means said object is moving in the opposite direction of the positive x-axis. It is possible for the object to still be in the positive position as it's moving with a negative velocity

pls help asap pls explain. Just before opening her parachute a skydiver having a mass of 50 kg reaches terminal velocity. Calculate the force of air resistance if the buoyant force is 20 N. Be careful! Use the skydiver’s mass to calculate his/her Fg (force of gravity).

Answers

Answer:

490N

Explanation:

Given that,

Mass of a skydiver, m = 50 kg

Buoyant force = 20 N

When the skydiver reaches the terminal velocity, net force on her is equal to 0. So, air drag is equal to the weight of the skydiver.

D = mg

Putting all the values,

D = 50 × 9.8

D = 490 N

So, the force of air resistance is 490 N.

A 1500 kg car traveling at 15m/s to the south collides with a 4500 kg truck that is initially at rest at a stoplight. the car and truck stick together and move together after the collision, what is the final velocity of the two vehicles

Answers

Answer: 3.75 m/s

Explanation:

Here's what you know: The car has mass 1500 kg, and initial velocity 15.0 m/s.  The truck has mass 4500 kg and initial velocity 0 m/s.  The final mass is 6000 kg (4500 kg plus 1500 kg, because they stick together) and we are looking for the final velocity.  Using the formula p = mv, and the concept that p before equals p after, the p of the car plus p of the truck equals the p of them together. So, 1500 x 15 + 4500 x 0 = 6000 x v final.  22500 = 6000 v, and v = 3.75 m/s.  The velocity is positive, and the initial velocity of the car was positive, so the two vehicles together are traveling to the south just like the car was initially.

A 15-N force and a 45-N force act on an object in opposite directions
What is the net force on the object? *

Answers

Answer:

30-N

Explanation:

Because they are both acting on an object going opposite directions, then you simply subtract the 15 from 45 as 45N of force is stronger than 15N of force.

The net force on the object is 30 Newton due to these two opposite forces.

What is force?

The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the Force. The Newton is the SI unit of force.

Here, a 15-N force and a 45-N force act on an object in opposite directions.

The net force on the object  due to these two opposite forces is = 45 N - 15 N
