Answer:
F = 8.48 x [tex]10^{-18}[/tex] N
Step-by-step explanation:
The force on an electron in a magnetic field can be determined by;
F = qvB Sin θ
where: e is the electron, v is its velocity, B is the measure of the magnetic field, and θ is the angle of its path.
Thus,
q = -1.6 x [tex]10^{-19}[/tex] C
v = 106 m/s
B = 0.5 T
θ = [tex]90^{o}[/tex]
So that,
F = 1.6 x [tex]10^{-19}[/tex] x 106 x 0.5
= 8.48 x [tex]10^{-18}[/tex] N
The force on the electron crossing the uniform magnetic field is 8.48 x [tex]10^{-18}[/tex] N.

Sergio has ppp paintings in his art collection. He and other local painting collectors agreed to donate a total of 484848 paintings to the local museum. Each of the 121212 collectors will donate the same number of paintings.
Answer:
Total paintings Sergio have in his art collection after his donation = p - 4
Step-by-step explanation:
P.S - The exact question is -
Given -Sergio has p paintings in his art collection. He and other local painting collectors agreed to donate a total of 48 paintings to the local museum. Each of the 12 collectors will donate the same number of paintings.
To find - How many paintings will Sergio have in his art collection after his donation ?
Proof -
Given that,
Total collectors = 12
Total painting that has to denote = 48
⇒12 collectors donate paintings = 48
⇒1 collector donate painting = [tex]\frac{48}{12}[/tex] = 4 paintings
∴ we get
Each collector donate paintings = 4
⇒Sergio donate total paintings = 4
Now,
Total pictures Sergio have = p
After donating,
Total left paintings = p - 4
∴ we get
Total paintings Sergio have in his art collection after his donation = p - 4
Find the height of a cone with a diamater of 12m whose value is 151 meters cubed, then round it to the nearest meter
Answer:
Height= 4m (nearest meter)
Step-by-step explanation:
[tex]\boxed{volume \: of \: cone = \frac{1}{3} \pi {r}^{2}h }[/tex]
Diameter= 2(radius)
Given that the diameter is 12m,
radius of cone
= 12 ÷2
= 6m
Let the height of the cone be h meters.
[tex]151 = \frac{1}{3} \pi(6^{2} )(h)[/tex]
[tex]151 = 12\pi h[/tex]
[tex]h = \frac{151}{12\pi} [/tex]
h= 4.0054 (5 s.f.)
Thus, the height of the cone is 4m. (nearest meter)
How many square feet of outdoor carpet will we need for this hole?
Answer:
42 sq ft
Step-by-step explanation:
First, I will do the small triangle on the right.
2 x 3 = 6
6/2 = 3 sq ft
Next the large rectangle.
11 x 3 = 33 sq ft
Next the large triangle on the left.
3 x (11-7)
3 x 4 = 12
12/2 = 6 sq ft
Add them all together.
6 + 33 + 3 = 42

Please help!! I already missed two!
Answer:
30,40,50
Step-by-step explanation:
We use the Pythagorean theorem to find out if they would be sides of a right triangle
the Pythagorean theorem states that the two shorter sides squared added together equal the longest side square
for 30, 40 , 50
[tex]30^2=900\\40^2=1600\\1600+900=2500\\50^2=2500\\2500=2500[/tex]
2500=2500 therefore that is the correct answer

Step-by-step explanation:
Triangle RST and its image, triangle R’S’T’, are graphed on the coordinate grid below.
Which rotation, using the origin as the center of rotation, transformed RST to R’S’T’?
A. a 90° clockwise rotation
B. a 90° counterclockwise rotation
C. a 45° clockwise rotation
D. a 45° counterclockwise rotation
Answer:
B. a 90º counterclockwise rotation
Step-by-step explanation:
You can tell that it moves 90º and it moves in a counterclockwise direction because from RST to R’S’T’ it moves left to right. That is counterclockwise when you look it up.
Hope this helps!!! :)))))

Tim's family traveled 3 10 of the distance to his aunt's house on Saturday. They traveled 3 7 of the remaining distance on Sunday. What fraction of the total distance to his aunt's house was traveled on Sunday?
Answer: 3/10
Step-by-step explanation:
From the question, we are informed that Tim's family traveled 3/10 of the distance to his aunt's house on Saturday. Then, the remaining distance will be:
= 1 - 3/10
= 7/10
Since they traveled 3/7 of the remaining distance on Sunday, the fraction of the total distance to his aunt's house that was travelled on Sunday will be:
= 3/7 × 7/10
= 3/10

Find the distance between the two points rounding to the nearest tenth (if necessary).
(−1,−2) and (5,2)
Answer:
7.2 units
Step-by-step explanation:
To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the given values of (-1, -2) & (5, 2)
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(5 - (-1))² + (2 - (-2))²]
Simplify the parentheses.
d = √[(5 + 1)² + (2 + 2)²]
d = √[(6)² + (4)²]
Simplify the exponents.
d = √[36 + 16]
Add.
d = √[52]
Evaluate the radical.
2√13 or 7.2111
Round the decimal.
7.2 units

You need 3 sticks of butter for every 24 cookies you bake.
Complete the table using equivalent ratios.
3. 24
16
5. 32
Step-by-step explanation:
3 sticks of butter make 24 cookies
which means we multiplied 3 by 8
then we devide 16 cookies by 8 which is 2 (as you did)
therefore 5 multiplied by 8 equals 40

I'll just do red for now, but if you're very desperate I guess I'll help with a few more lol. It's just a lot of typing and my computer is at 6% :)
RATIO:
Ratios are another way of comparing things. It's almost like a fraction, except that it can look like x:y.
I'm guessing you're comparing all of the reds to the total amount, which should be 39. Put 5 in for x and 39 for y to make it look like 5:39.
DECIMAL:
Oh decimals are so fun...
Just divide 39 by 5. The answer to red's decimal is 7.8.
PERCENTAGE:
Percentage can come a little bit confusing to some people, so I'll explain this the best I can.
Basically, all you have to do to find it is divide the number you're making into a percentage by the total amount, then multiply it.
5/39 x 100
0.1282051282 x 100
12.8205128205
I'm going to the nearest hundredth which is 12.82.
Your percentage is %12.82
(If you're rounding to the nearest whole number, it'll be %13)
THEORETICAL:
For this simplify your ratio. 5/39 cannot simplify, so just leave it as 3/39.
Sorry, sometimes I come out a little confusing, so just try not to think too hard about what I'm trying to say if you're confused more lol. Anyway my computer is going to die so I'll go now :)
Find the diameter of a circle with a circumference of 27 centimeters. Use 3.14. Round to the nearest tenth.
Answer:
The diameter of the circle is 5.6 cm
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle and clear d:
c = circumference = 27cm
d = diameter
π = 3.14
c = π * d
d = c / π
we replace with the known values
d = 27cm / 3.14
d = 5.599
The diameter of the circle is 5.599 cm
round to the nearest tenth
d = 5.599 cm = 5.6 cm
The diameter of the circle is 5.6 cm
Which statement best describes the expression 3 + 2 + y? (1 point) a The quotient of y and the sum of 3 and 2 b The quotient of the sum of 3 and 2 and y с The sum of 3 and the quotient of 2 and y d The sum of 3 and the quotient of y and 2
Answer:
с. The sum of 3 and the quotient of 2 and y
Step-by-step explanation:
Given that: 3 + 2 ÷ y
It would be observed that operation addition comes before division, but with respect to BODMAS; division (D) comes before addition (A).
Thus,
3 + 2 ÷ y = 3 + [tex]\frac{2}{y}[/tex]
and [tex]\frac{2}{y}[/tex] is the quotient of 2 and y
Therefore, the appropriate statement that would describe the expression is; the sum of 3 and the quotient of 2 and y. This is option C in the given question.
what is 5% of 30 and what is 25% of 30 and what is the difference?
Answer:
5% of 30 is 1.5
25% of 30 is 7.5
25% is one quarter. 5% is a fifth of a quarter.
Answer:
5% of 30 is = 30 x 0.05 = 1.5
25% of 30 is 30 x 0.25 = 7.5
The difference is 6
Which number will be closest to 14? A. 13.4 B. 13 1\2 C. 13.08 D. 13 2\5
Answer:
13.08
Step-by-step explanation:
Its the closest
Answer:
13.5
Step-by-step explanation:
Convert fractions to decimals.
13 and 8/100 is 13.08
13 1/2= 13.5
13 2/5= 13.4 (13.4 and 13 2/5 are the same)
So your options are 13.5, 13.4, 13.08.
Round decimals up or down. When rounding to the nearest hundredth (50 and above rounds up, below fifty rounds down. Ex. 13.5 (13.50) rounds to 14 whereas 13.4 (13.40) and 13.08 round back down to 13)
