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.

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.

Therefore, it is important to stay hydrated when you are sick.

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.

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

Answer: It's Friday night and Skyler has been assigned the noble task of baby-sitting Casey, his 2-year old brother. He puts a crash helmet on Casey, places him in the red wagon and takes him on a stroll through the neighborhood. As Skyler starts across the street, he exerts a 52 N forward force on the wagon. There is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N. Construct a free body diagram depicting the types of forces acting upon the wagon. Then determine the net force, mass and acceleration of the wagon.

Explanation:

When Skyler exerts a force of 52 N on the wagon and there is a 24 N resistance force and the wagon and Casey have a combined weight of 304 N then Net force, mass and acceleration of the wagon will be 305.2 N, 31.02kg and 0.9 m/s² resp.

Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. when net force acting on body is zero then it is called as balanced force and net force on the body is non zero then it is called as unbalanced force. unbalanced force are responsible for the motion of the body.

in this problem, Skyler is applying 52 N force to a wagon, there is resistance of 24N of force. Combined Wight is 304 N is directed downwards. a vector diagram is shown in the figure which gives the Net force.

the resultant force between resistance and applied force

F = 52 - 24 = 28N... means total of 28N of actual force is applied on the wagon in x direction.

There is downward force as weight, hence magnitude of net force acting on the wagon is.

F²(net) = F₁²+F₂² + F₁F₂cosθ

θ = 90, cos 90 = 0

F²(net) = F₁²+F₂²

F²(net) = 28² + 304²

F²(net)  = 93200

F (Net) = [tex]\sqrt{93200\\[/tex] = 305.2 N

To get mass and acceleration,

weight W = mg

304 = m*9.8

m = 31.02 kg mass of the wagon is 31.02kg

F = ma

28 = 31.02*a

a = 0.9 m/s²

Acceleration of the wagon is 0.9 m/s². this is forward acceleration.

Hence Net force, mass and acceleration of the wagon is 305.2 N, 31.02kg and 0.9 m/s² resp.

Answer::27 km per hour West + 17 km per hour North

Explanation:

:27 km per hour West + 17 km per hour North

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.

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.

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

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]
