SOMEONE PLEASE ANSWER IM DESPRATE AND NOONES ANSWERING MY QUESTIONS, ILL GIVE U A PICTURE OF MY CAT TO BRIGHTEN YOUR DAY AND BRA

INLIEST+THANKS/5STARS ON ALL OF YOUR ANSWERS IF U ANSWER THIS FAST!!
To investigate absorption, Hector cuts two rectangles from five different-colored sheets of construction paper. He then staples three sides of each pair of rectangles to make a pocket and inserts a thermometer into each.

He takes the thermometers in the construction paper pockets outside, where it is clear and sunny. The initial temperature of each thermometer is 22°C. The image shows the thermometers after being outside for 15 minutes.

A thermometer in black paper reads 38 degrees Celsius, a thermometer in white paper reads 24 degrees Celsius, a thermometer in green paper reads 29 degrees Celsius, a thermometer in red paper reads 31 degrees Celsius, and a thermometer in blue paper reads 33 degrees Celsius.
Complete Hector's table by recording the final temperature and calculating the temperature change for each thermometer.

Answer:

Black Final: 38; Change: 16

White Final: 24; Change: 2

Green Final: 29; Change: 7

Red Final: 31: Change: 9

Blue: 33: Change: 11

Explanation:

Black Final: 38

Black Change: 38 - 22 = 16

White Final: 24

White Change: 24 - 22 = 2

Green Final: 29

Green Change: 29 - 22 = 7

Red Final: 31

Red Change: 31 - 22 = 9

Blue Final: 33

Blue Change: 33 - 22 = 11

A piece of styrofoam has a charge of 0.002 mC and is placed 0.5 m from a grain of salt with a charge of 0.03 nC. How much electr
aleksklad [387]

Answer:

2.16×10⁻⁶ N

Explanation:

Applying,

F = kqq'/r² (coulomb's Law)....................... Equation 1

Where F = electrostatic force, k = coulomb's constant, q = charge on the styrofoam, q' = charge on the grain of salt, r = distance between the charges.

From the question,

Given: q = 0.002 mC = 2.0×10⁻⁶ C, q' = 0.03 nC = 3.0×10⁻¹¹ C, r = 0.5 m

Constant: k = 8.99×10⁹ Nm²/C²

Substitute these values into equation 1

F = (2.0×10⁻⁶)(3.0×10⁻¹¹)(8.99×10⁹)/0.5²

F = 2.16×10⁻⁶ N

Explain how neurons convey information using both electrical and chemical signals.
8090 [49]

Answer:

Explanation:

Neurons communicate via both electrical signals and chemical signals. The electrical signals are action potentials, which transmit the information from one of a neuron to the other; the chemical signals are neurotransmitters, which transmit the information from one neuron to the next.

The electrical signal travels down the axon to the axon terminals where it tells the vesicles to release the neurotransmitters into the synaptic cleft which travel to the receptors of the receiving cell which releases the second messengers

11. एक समान चुम्बकीय क्षेत्र में लम्बवत प्रवेश करने वाले किसी आवेशित कण द्वारा प्राप्त वृत्तीय पथ की
mojhsa [17]

Answer:

<h2> r=mv/Be</h2>

Explanation:

If a positive charge enters a magnetic field at 90 degrees the charge is deflected in a circular path by a force that acts perpendicular to it in line with Flemings right-hand rule

to derive the radius of the path of the charge we apply

F= mv^2/r=Bev

where

m= mass of the electronic charge

e=charge

B=magnetic field

v=average speed

r=radius

 

rearranging we have

r=mv^2/Bev

r=mv/Be
