A 0.025 kg bullet enters a 2.35-kg watermelon with a speed of 217 m/s
and exits the opposite side with a speed of 109 m/s. If the melon was
originally at rest, then what speed will it have as the bullet leaves its
opposite side?
Answers
Answer:
1.15m/s
Step-by-step explanation:
Given data
m1=0.025 kg
m2= 2.35kg
u1= 217 m/s
v1= 109 m/s
u2= 0
v2=???
Applying the law of conservation of linear momentum
m1u1+m2u2=m1v1+m2v2
substitute
0.025*217+2.35*0= 0.025*109+2.35*v2
5.425= 2.725+ 2.35v2
5.425-2.725=2.35v2
2.7=2.35v2
divide both sides by 2.35
v2= 2.7/2.35
v2=1.15 m/s
Hence the speed of the watermelon will be 1.15m/s

How much net work is required to accelerate a 1000 kg from 20 m/s to 30
m/s?
Answers
Answer:
Work= force(F) * distance (s)
weight is a force and so
F=weight=mass *acceleration due to gravity
=1000*10=10000N
S=?
To find s,
F= ma
a=F/m=10000/10
a=10m/s²
Using Newton's third equation of motion
v²= u²+2as
30²= 20²+2*10*s
900–400=20s
500=20s
s=500/20= 25m
Work =F*s
Work=10000*25
Work= 250000J or 250KJ

Find the equation of a parabola whose vertex is at (−1, 7), whose axis of symmetry is
x = −1, and whose y-intercept is (0, 10). Write your answer in vertex form.
Answers
Answer:
Step-by-step explanation:
The axis of symmetry is vertical, so the parabola is vertical.
Vertex-form equation for a vertical parabola with vertex (h,k):
y = a(x-h)² + k
axis of symmetry: x = h
Apply your data and solve for h, k, and a.
vertex (-1,7)
h = -1
k = 7
y = a(x+1)² + 7
(0,10) is a point on the parabola
10 = a(0+1)² + 7
a = 3
The equation becomes
y = 3(x+1)² + 7
To prepare for a lab experiment, Ted is making a solution that uses two types of concentrations of HCI ( hydro boric acid) 80 ml of 50% HCI solution, and 120 mlL of 20% HCI solution. What is the HCI concentration of the mixes solution
Answers
Answer:
32%
Step-by-step explanation:
50% of the first solution is HCL, so it has
80 ml x 50% = 80 ml x 0.5 = 40 ml of HCL
Similarly the second solution has 20% of HCL, so
120 ml x 20% = 120 ml x 0.2 = 24 ml of HCL
The combined solution will have 40 ml + 24 ml = 64 ml of HCL.
The total volume of the 2 solutions is 80 ml + 120 ml = 200 ml.
We can now calculate the concentration of HCL in the mixed solution, by dividing the volume of HCL by the total volume of the solution,
64 ml / 200 ml = 0.32 = 32%

You select 6 cards randomly from a deck of 52 cards. What is the probability that all of the cards selected are face cards
Answers
Answer:
Step-by-step explanation:
There are two different techniques that I can think of for arriving at the answer. The first method utilizes combination, sometimes referred to as the “choose” operator. First, we need to know how many 6 cards hands are possible, which can be calculated using 52 choose 6, which in notation looks like (526) =20,358,520 . This is our denominator.
Now that we know how many total 6 cards hands there are in a normal deck, we need to find the numerator, which is how many 6-card hands can be made up of all hearts. Since there are 13 hearts in the deck, we can find that number with (136) =1,716 .
Completely written out in mathematical notation, the probability of drawing 6 cards that are all hearts, appears as follows:
(136)(526)=171620358520≈0.0000843≈0.00843%
__________________________________________________
The second method that results in the same value can be found by multiplying together the chances of drawing the individual cards at each step, for example, there is a 1352 chance of the first card drawn being a heart, 1251 for the second, and so on.
This second method looks like:
1352×1251×1150×1049×948×847≈0.0000843≈0.00843
Incidentally, 13!46!7!52! is another way to notate this second method.
Personally, I find the first method to be cleaner and easier to work with, but some may find the second more intuitive.
Answer: 11/51
Step-by-step explanation: After you've picked the first card, if it's a face card then there are only 11 faces cards left, out of a total of 51. So the probability of the next card also being a face card is 11/51.

What is the molecular weight of the substance?
g/mol
а
1.76 g/mol
b. 177.6 g/mol
с
17.755 g/mol
d 177.55 kg/mol
Answers
Answer:
177.6 g/mol
Step-by-step explanation:
The molecular weight of the substance is 177.55 g/mol.
Option B is the correct answer.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
The molecular weight (MW) of the substance can be calculated by dividing the mass of the sample by the number of moles:
MW = mass/moles
MW = 0.03551 kg / 0.2000 moles
MW = 0.17755 kg/mol
However,
The answer is given in grams per mole, so we need to convert the result to g/mol.
So,
1 kg = 1000 g
MW = 0.17755 x 1000 g/mol
MW = 177.55 g/mol
Therefore,
The molecular weight of the substance is 177.55 g/mol.

including taxes. To pay for the television, he will use
a payment plan that requires him to make a down
payment of $150, and then pay $70.50 each month
for 6 months. What is the percent increase from the
original cost of the television to the cost of the
television using the payment plan?
Answers
Calculate the total he will pay:
70.50 x 6 months = 423
423 + 150 = 573
He pays a total of 573
Find the difference from what he pays to what the actual price was:
573 - 400 = 173
Divide the difference by the actual price:
173 / 400 = 0.4325
Multiply by 100:
0.4325 x 100 = 43.25% increase
