Yes, as long as it hasn't reached its maximum speed. Think of a car going 30mph, it can remain at this speed and travel at a constant rate; however, the car could also increase it's speed further. Hope this answers your question.

The average density of the body of a fish is 1080 kg/m3. To keep from sinking, the fish increases its volumeby inflating an inte
Dimas [21]

Answer:

f = 8 %

Explanation:

given,

density of body of fish = 1080 kg/m³

density of air = 1.2 Kg/m³

density of water = 1000 kg/m²

to protect the fish from sinking volume should increased by the factor f

density of fish + density of water x increase factor = volume changes in water                                                    

1080 +f x 1.2 =(1 + f ) x 1000                

1080 + f x 1.2 = 1000 + 1000 f      

998.8 f = 80                                  

f = 0.0800                            

f = 8 %                                        

the volume increase factor of fish will be equal to f = 8 %

What is the value of R2 in this parallel circuit? (5 stars)
o-na [289]

Answer:

20 Ω

Explanation:

Voltage, current, and resistance are related by Ohm's law:

V = IR

40 V = (4 A) R

R = 10 Ω

The total resistance of the circuit is 10 Ω.

Resistors in parallel have a total resistance of:

1/R = 1/R₁ + 1/R₂

1 / (10 Ω) = 1 / (20 Ω) + 1/R₂

R₂ = 20 Ω

A car is traveling in a circular curve on a horizontal road at constant speed. Name the force that is responsible for causing it
I am Lyosha [343]
The correct answer is
<span>c the friction force from the road 

In fact, the friction force between the road and the tires prevents the car from "sliding away" in a straight line and keeps it in circular motion, acting as centripetal force.</span>

Answer this And you will get The brainiest
Scrat [10]

Answer:

see below

Explanation:

let one direction be negative and the other direction be positive

so

right = positive

left = negative

up = positive

down = negative

thus

d) -80 + 100 = 20 N

e) 35 - 55 = -20 N

hope this helps, please mark it brainliest

What is the Coriolis Force?
lys-0071 [83]

It's a virtual force ... one that seems to be there but isn't really there.

When something tries to fly or flow straight, through a rotating neighborhood, it ends up flying or flowing in a curved path, AS IF there were a force acting on it to make it curve. THAT apparent force is the Coriolis force.

It's what makes air, flowing away from high pressure or into low pressure, form the big rotating pressure systems on the rotating Earth.
