Answer:

Correct answer is A.

The higher the enzyme, the higher the Vmax

Explanation:

Although, in the absence of enzyme, the rate of a reaction(Vmax) increase linearly with substrate concentration. The reaction rate is given as dp/dt.

The rate of a reaction involving enzyme also increases.

At low enzyme concentrations or high substrate concentrations, all of the available enzyme active sites could be occupied with substrates. Therefore, increasing the substrate concentration further will not change the rate of diffusion. In other words, there is some maximum reaction rate (Vmax) when all enzyme active sites are occupied. The reaction rate will increase with increasing substrate concentration, but must asymptotically approach the saturation rate, Vmax. Vmax is directly proportional to the total enzyme concentration, E

Answer:

Below

Explanation:

1) To find the average velocity of an object you can use this formula :

     v = ∆displacement / ∆time

     v = 200 m / 5 s

     v = 40 m/s

The average velocity of the turtle is 40 m/s

2) To find the distance an object can travel you can use this formula :

     d = (∆velocity)(∆time)

     d = (20m/s)(5s)

     d = 100 m

The cheetah can run 100 meters in 5 seconds

3) To find the amount of time it takes for an object to move :

     t = ∆displacement / ∆velocity

     t = 5mi / 20 mph

     t = 0.25 h

It would take this car 0.25 h to travel 5 miles at 20 mph

4) To find how far an object can go :

     d = (∆velocity)(∆time)

     d = (20mph)(3h)

     d = 60 mi

The car can drive 60 miles driving 20 mph for 3 hours

5) To find how far an object can go :

     d = (∆velocity)(∆time)

     d = (20mph)(30min)

     d = (20mph)(0.5h)

     d = 10 mi

The car can drive 10 miles driving 20mph for 30 minutes

6) To find how long it would take :

     t = ∆displacement / ∆velocity

     t = 10 m / 50 m/s

     t = 0.2 s

It would take the train 0.2 seconds for a train to travel 10 m at 50 m/s

7) To find how far :

     d = (∆velocity)(∆time)

     d = (670,000,000 mph)(1 yr)

     d = (670,000,000 mph)(8760 h)

     d = 5869200000000 mi

1 light year is 5869200000000 miles

Hope this helps! Best of luck <3

Brilliant_brown [7]

Answer:

Electric Field Strength E₀ = E₀ = Constant

Explanation:

The Electric Filed Strength E₀ to an Infinite uniformly charge large sheet is constant how far is it i.e. it is independent of the distance away from the uniformly charge sheet.

Formula: E₀ = σ / 2 ε₀

a horizontal force of 100N is required to push a crate across a factory floor at a constant speed. What is the net force acting
Bas_tet [7]

If the crate is moving along the floor in the same direction with a constant speed, it is in dynamic equilibrium. Equilibrium means there is no net force acting on the crate.

Since there is no net force on the crate, there must be a friction force on the crate equal in magnitude and opposite in direction to the applied horizontal force. Therefore the force of friction acting on the crate is 100N.
