according to newton’s second law, if there is a net force, there will be
Answer:
The object will have an acceleration and the object's velocity will change.
Explanation:
If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.

Please help! Why is the air pressure lower on top of the airfoil?
Please don't answer if you don't know thanks!
Answer: When air passes both above and below the airfoil, the air on top moves faster because of the curve, causing it to have a lower air pressure. This is according to Bernoulli’s principle, which states that faster moving air has less pressure than slower moving air. Also This is what causes the airplane to lift into the air.
Explanation:
Answer:

The best description of the role of glucose in the body is that it is the food converted into fuel. Details about role of glucose can be found below.
What is cellular respiration?Cellular respiration is the process by which living organisms obtain energy for their daily activities by breaking down food molecules in their cells.
The food ingested by living organisms is digested into the simplest form called glucose. The glucose is then broken down during cellular respiration.
During cellular respiration, glucose is broken down to produce energy (ATP), which is the fuel for metabolic activities in the body.

A monkey on a raft is crossing a river that flows to the east at 8.0m/s. His top paddling speed is 12.0m/sec. He points due south and attempts to cross. If the river is 120m wide, how far downstream will he end up when he reaches the other side?
The relation of uniform movement allows to find the result for the distance that descended when crossing the river is:
d = 180 m
Given parameters
The velocity of the river [tex]v_r[/tex] = 8.0 m / s towards the East The speed of the monkey [tex]v_m[/tex] = 12.0 m / s towards the south River width x = 120 mTo find
Distance downstream when crossing.
Velocity is a vector magnitude, it has modulus and direction, therefore vector algebra must be used.
The velocities are constant, let's use the uniform motion relation.
v = [tex]\frac{d}{t}[/tex]
In the attached we have a diagram of the movement. Let's calculate the time to cross the river.
[tex]v_r = \frac{x}{t}[/tex]
[tex]t= \frac{x}{v_r}[/tex]
t = [tex]\frac{120}{8.0}[/tex]
t = 15 s
The time is a scalar it is the same for the two movements, let's find how much it has descended in this time.
[tex]v_m = \frac{d}{t}[/tex]
d = [tex]v_m t[/tex]
d = 12.0 15
d = 180 m
In conclusion, using the uniform motion relationship we can find the result for the distance that descended when crossing the river is:
d = 180 m

an audi car advertisement states its car can accelerate from a starting velocity of rest to an ending velocity of 70m/s in 35 seconds. what is the car acceleration?
Answer:
279 m/s
Explanation:
Answer:
2m/s^2
Explanation:
A=(u-v)/t
where u=final velocity and v=initial velocity and t=time
therefore u =70 and v=0 because the question said velocity of rest and finally t=35
so, (70-0)/35= 70/35=2

You are driving up an inclined road. After 3.0 km you notice a roadside sign that indicates that your elevation has increased by 160 m. What is the angle of the road above the horizontal?
Answer:
~3°
Explanation:
x^2 + 0.16^2 = 3^2
x^2 + 0.0256 = 9
x^2 = 8.9744
x = sqrt(8.9744) = 2.99... = ~3

How is an apple falling from a tree like the potential difference in a battery?
The gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object
The gravitational potential energy of a falling apple is maximum when the apple is at maximum height. As the apple begins fall to the ground the potential energy decreases and it will be transformed to kinetic energy.
[tex]P.E_i + K.E_i = P.E_f + K.E_f[/tex]
The potential difference in a battery is total energy stored in the battery.
Thus, the gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object.
Learn more about gravitational potential energy here: https://brainly.com/question/12314347
The similarity is that both the battery and the falling apple have stored energy.
We define the potential energy of an object as stored energy in that object.
A battery has potential energy, it is stored until you connect it to something and allow that energy to flow.
Similarly, when the apple is in the air it has potential energy, that will be transformed into kinetic energy as it falls (as the apple falls, its velocity increases, thus, the kinetic energy increases).
So both, the apple and the battery have stored energy, and that is the similarity between these two.
