Answer:

Average acceleration = 6m/s²

Explanation:

Given the following data;

Initial velocity, u = 4m/s

Final velocity, v = 22m/s

Time, t = 3 seconds

To find the average acceleration;

Acceleration = (v - u)/t

Substituting into the equation, we have;

Acceleration = (22 - 4)/3

Acceleration = 18/3

Acceleration = 6m/s²

What is the correct classification of a mixture in which both a solid and a liquid are visible?
stepan [7]
<span>The answer is a heterogeneous mixture. Mixtures can be homogeneous and heterogeneous. If a solid and a liquid of a mixture cannot be separated and the difference between them is not visible, it is called homogeneous mixture (or solution). If a solid and a liquid of a mixture are visible and can be separated easily, the mixture is called heterogeneous.</span>

You are given three resistors with the following resistances: R1 = 6.32 Ω, R2 = 8.13 Ω, and R3 = 2.29 Ω. What is the largest equ
andreyandreev [35.5K]

Answer:

The largest equivalent resistance yu can build using these three resistors is a Serie Resistance with the value of R= 16.74 Ω

Explanation:

Adding Resistances in serie is the way to build de largest equivalent value possible.

Rt= R1+R2+R3

Rt= 6.32 + 8.13 + 2.29

Rt= 16.74Ω

KIM [24]
The work performed on an object is the force multiplied by the distance it is moved, provided the movement is parallel to the force.  Since that is the case here, we can get the work by W=Fd=1900N x 0.23m = 437J.  This energy is used to split the wood.
