2 m/s²

Step-by-step explanation:

Step 1:

Let the initial velocity be 0 m/s and the final velocity be 8 m/s and the time traveled is 4 s.

From the basic science,

Acceleration = ( Final Velocity - Initial Velocity) / Time

Step 2:

Acceleration = (8-0)/4

2 m/s²

Tim says that every time you mutiply two

Sunny_sXe [5.5K]

Answer:

I disagree

Step-by-step explanation:

This is not true because when you multiply a number by one. It will give you its number. It may be a larger number than 1 but it is not bigger than both numbers. Also if you multiply 0 by a number. It will eventually give you the answer 0 .It will be smaller than the number you started with. eg 100x0 = 0

A temperature of –25°c is equivalent to:<br> a. 248 k.<br> b. 25 k.<br> c. –25 k.<br> d. 298 k.

SpyIntel [72]

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15;

So, T(K) = -25 + 273.15;

T(K) = 248.15;

The correct answer is a.

What is the length of side s of the square shown below?

zaharov [31]

Answer:

$A.\: 4 \sqrt{2}$

Step-by-step explanation:

$\sin \: 45 \degree = \frac{s}{8} \\ \\ \implies \: \frac{1}{ \sqrt{2} } = \frac{s}{8} \\ \\ \implies \: s = \frac{8}{ \sqrt{2} } = \frac{8 \sqrt{2}}{2} \\ \\ \implies \: \huge \: s = 4 \sqrt{2}$
