what produces pressure in a liquid
Answer:
1. The weight of the column of water above
2. Due to Gravity
(I would say there are two answers for this question)
Explanation:
1.
The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom of a reservoir is greater than the pressure acting near the top.
2.
Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Since a fluid has no definite shape, its pressure applies in all directions. Fluid pressure can also be amplified through hydraulic mechanisms and changes with the velocity of the fluid.
A girl standing 600m away from a cliff bangs two pieces of wood together and hears an echo 3.5 seconds later. Determine the speed of sound in that place
Speed = 342.86 m/s
EXPLANATION
s = v × t/2
600 m = v × 3.5 s/2
600 m × 2 = v × 3.5 s
1200 m = v × 3.5 s
v = 1200 m/3.5 s
v = 342.86 m/s

The speed of sound in that place 342.86 m/s
What is speed of sound?
The speed of sound is defined as the distance through which a sound wave’s point, such as a compression or a rarefaction, travels per unit of time.
given
distance of cliff= 600 m
time = 3.5 seconds
speed of sound = ?
distance = speed * time
distance travelled by the sound to come back to the place where the girl was standing will be = 600 * 2 m
speed = distance / time
speed = 600 * 2 m / 3.5 seconds
speed = 1200 / 3.5 = 342.86 m/s
The speed of sound in that place 342.86 m/s

Over the course of the 4 hours for which farmer Joe's tractor is pulling the heavy plow, the plow is gaining energy by virtue of its displacement --termed the Kinetic energy.
According to the question, Farmer Joe drives the tractor for 4 hours.
However, the tractor is connected to a heavy plow and is used to pull the plow across a rocky field.
The question requires that we determine if the plow is gaining or losing energy.
In the plow's state of rest, prior to when it is connected to the tractor and pulled by the tractor; the plow possess a form of energy by virtue of its position termed the Potential energy.However, the focus of the question is during the pulling action of the tractor on the plow.
As such, the plow now has a kinetic energy by virtue of its displacement..Ultimately, the plow is gaining energy as it is being pulled by the tractor and now has Kinetic energy.

he or she is right good jod
The velocity for the trip would be 31 km per hour, therefore the correct answer is option B.
What is displacement?An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.
As given in the problem, on a trip you travel at a constant speed of 50 kilometers per hour North for 1 hour. Then you turn West and travel at a constant speed of 40 kilometers per hour for 2 hours.
The final displacement of the trip = √(50² + 80²)
= 94.34 kilometers
The velocity of the trip = total displacement of the trip / time period
=94.34 kilometers / 3
= 31 kilometers per hour
Thus, the velocity of the trip would be 31 kilometers per hour.

C.
It is always easier to drink than to eat if you are sick.
D.
They are probably sick because they were dehydrated.

Answer:
A.
Explanation:
Drinking water usually helps with gaining hydration cause usually when you get sick you get weak. thats what u think though
Water will help expel toxins from the body that's why it is recommended to sick people to consume more water. Therefore, option (A) is correct.
Why is it important to stay hydrated during sick?Proper hydration can be helpful to the skin and mucous cell membranes play a barrier to stop bacteria from entering the body when sick with a virus. Fluid can also help decrease irritation when sneezing, coughing, and even breathing.
Water can help to regulate body temperature, maintain healthy skin and joints, digest food, and help the brain function at its best. Producing requires bodily fluids, like tears and saliva, and removing waste through sweat, and urination.
Dehydration can happen when we lose a high amount of bodily fluids than we’re consuming. This can occur through bodily functions that bring the loss of fluids and electrolytes.

What can we say when one force
is greater than another force?
A. There is no net force.
B. There is no change in motion.
C. There is a change in motion.
D. The forces are in equilibrium.
When one force is greater than another force, we can say that there is a change in motion. The correct answer is option C: "There is a change in motion."
According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. When one force is greater than another force, the net force acting on the object is not zero. If the net force acting on an object is not zero, it will cause the object to accelerate in the direction of the larger force. This acceleration leads to a change in motion. The object may speed up, slow down, change direction, or a combination of these.
Option A, "There is no net force," is incorrect because if one force is greater than another, there is a net force acting on the object.
Option B, "There is no change in motion," is incorrect because, as explained above, a greater force leads to a change in motion.
Option D, "The forces are in equilibrium," is incorrect because if one force is greater than another, the forces are not balanced, and the object is not in equilibrium.
Therefore, the correct statement is that there is a change in motion when one force is greater than another force.

Automobile manufacturers, such as Nissan and Toyota, incorporate safety features into their vehicles. Crumple zones in the engine compartment and air bags are two examples of safety technology designed to protect driver and passengers involved in a collision. How do these design features impact the formula above and the force of impact? They decrease the force of impact by providing a cushion during the impact. Smaller force = lower momentum. They decrease the force of impact by extending the time it takes to stop the driver and passenger. Longer time = less force. It takes a longer time for the velocity of the vehicle to decrease, therefore the force is less. Decrease in velocity = less force. When a car rebounds it undergoes a greater change in velocity and the force is decreased. Lower force = greater change in velocity.

A space ship cruises at a constant velocity of 33,155 km/hr for 22.5 minutes. How far does the ship travel in that
time? State your result in kilometers.
Answer:
12,433 km
Explanation:
I got this by doing 33,155 and dividing it by 60, which is km per minute, then I did 552.583333, which is km per minute and multiplied it by 22.5, which equals 12,433 km
To check this you can do 12,433 times 2, which is 45 minutes and then use 552.583333, which is per minute, and multiplying by 15, which is 15 minutes, then add
(12,433 x 2 = 24,866) add 8288.75 [15 minutes] and that gets you 33,155
(Brainiest and thanks are very much appreciated for the effort put in)
E) The displacement is always equal to the distance traveled.
You drive 6.00 km at 50.0 km/h and then another 6.00 km at 90.0 km/h.
a) What is the total distance traveled?
Answer:
you just calculate the time in the two cases then add. I decided to convert into minutes and seconds
Differentiate the followingy= 14t^2-t^2/2+5t-3dy/dt=?
I'm going to assume you mean
[tex]y = 14t^2 - \dfrac{t^2}{2+5t} - 3[/tex]
Taking the derivative with respect to t on both sides gives
[tex]\dfrac{\mathrm dy}{\mathrm dt} = 2\cdot14t - \dfrac{(2+5t)(2t)-t^2(5)}{(2+5t)^2} - 0 \\\\ \dfrac{\mathrm dy}{\mathrm dt} = \boxed{28t - \dfrac{4t+5t^2}{(2+5t)^2}}[/tex]
You could go on to expand the rational expression into partial fractions. One way to do this:
[tex]\dfrac{5t^2 + 4t}{(2 + 5t)^2} = \dfrac{t(5t+2) + 2t}{(2+5t)^2} \\\\= \dfrac{t}{2+5t} + \dfrac{2t}{(2+5t)^2} \\\\= \dfrac15 \cdot \dfrac{t}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \cdot \dfrac{t+\frac25-\frac25}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \left(1 - \dfrac{2}{2+5t}\right) + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 - \dfrac{2}{10+25t}+ \dfrac{2t}{(2+5t)^2}[/tex]
and this would give
[tex]\dfrac{\mathrm dy}{\mathrm dt} = 28t - \dfrac15 + \dfrac2{10+25t} - \dfrac{2t}{(2+5t)^2}[/tex]
