White raven [17]2 years ago
6 0

Answer:

For an object to accelerate, appropriate force must be applied to the object to cause it to change it’s velocity if it’s already in motion. However, to cause it to overcome static friction if it is at rest, and cause it to change it’s velocity

Can you help me answer this?
Pavel [41]
The answer is D. If you aren't consistent with your drop positions, then your data may be invalid. To be frank: it basically screws over the experiment.

What is the length of an aluminum rod at 65°C if its length at 15°C is 1.2 meters? A. 0.00180 meter B. 1.201386 meters C. 1.2
Deffense [45]

Answer:

Option B is the correct answer.

Explanation:

Thermal expansion

            \Delta L=L\alpha \Delta T

L = 1.2 meter

ΔT = 65 - 15 = 50°C

Thermal Expansion Coefficient for aluminum, α = 24 x 10⁻⁶/°C

We have change in length

          \Delta L=L\alpha \Delta T=1.2\times 24\times 10^{-6}\times 50=1.44\times 10^{-3}m

New length = 1.2 + 1.44 x 10⁻³ = 1.2014 m

Option B is the correct answer.

To lower the voltage from a "120 V" outlet, what is used (first, at least) in most situations
nasty-shy [4]

Answer:

B. Transformer

Explanation:

A transformer is a device that is used to either raise or lower voltages and currents in an electrical circuit. In modern electrical distribution systems, transformers are used to boost voltage levels so as to decrease line losses during transmission. It basically trades voltage for current in a circuit, while not affecting the total electrical power. This means it takes high-voltage electricity with a small current and changes it into low-voltage electricity with a large current, or vice versa.

If Phoenix, Arizona, experiences a cool, wet day in June, does that mean the regions climate is changing?
jenyasd209 [6]
It doesn't mean that the climate is changing, it is probably just the morning dew.
