Acceleration = (change in speed) / (time for the change)

Change in speed = (speed after the change) - (speed before the change)

Change in speed = (65 m/s) - (35 m/s)  =  30 m/s

Acceleration = (30 m/s) / (5 s)

<em>Acceleration = 6 m/s²</em>

Anestetic [448]

Answer:

Explanation:

Folic acid is the form of folate found in vitamin supplements and fortified foods. Fortified foods, also called enriched foods, are foods that have specific nutrients added to them.

Neural tube defect happen when the tissues and bone around the brain and spine do not grow well. Neural tube can happen in the third and fourth week after conception (the first or second week after your first missed period). This could be before you know that you are pregnant.

Folic acid lowers the risk of your unborn baby having a neural tube defect . Neural tube are a group of serious birth defects that affect a baby’s spinal cord, brain and skull. Some babies with severe Neural tube defect birth are stillborn or do not survive long after birth. Spina Bifida is the most common Neural tube defect.

Tresset [83]

Answer:

8.4 kW

Explanation:

Using the Stefan-Boltzmann law,

P = εAσT4

Where:  

P: Radiation Energy

ε: Emissivity of the Surface. Check emissivity table below of common materials.

A: Surface Area, in m^2.

σ: Stefan-Boltzmann Constant, σ=5.67 × 10-8 W/m2•K4

T:  Temperature

Plugging in values,

P = 0.85 x 3.328 x 5.67 x 10^(-8) x 205

P = 8383 W or 8.4 kW

A 4810 kg demolition ball swings at the end of a 12.3 m cable on the arc of a vertical circle. At the lowest point of the swing,
faust18 [17]

The tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.

<h3>Tension in the cable</h3>

The tension in the cable supporting the swing of the ball is calculated as follows;

T = mg + mac

T = mg + m(v²)/r

T = (4810 x 9.8) + (4810 x 1.06²)/12.3

T = 47,577.4 N

Thus, the tension in the cable supporting the swing of the ball in the given vertical circle is 47,577.4 N.
