Answer:
<h2>b) 3.48 N approx.</h2>
Step-by-step explanation:
<em>The bird will experience a centripetal force, this is the force exerted on a body that moves through a curve path.</em>
Fc=centripetal force
m=mass
v=velocity
r=radius
Step one:
given data
mass of bird m=0.3kg
the radius of curve r= 20m
velocity v= 15 m/s
Substituting we have
<u>The force is 3.37N</u>
Answer:
19/2
Step-by-step explanation :
U divide the numerator and the denominator by the same number which is 3
57 divided by 3 = 19
6 divid by 3 = 2
So the answer is 19/2
Answer:
She has 2 1/24 meters of ribbon
Step-by-step explanation:
Skye has 12 1/4 meters of ribbon, and she uses 2/3 of that.
To know how much she uses we have to multiply the total by the fraction she uses:
12 1/4 * 2/3,
12 1/4 is the same as 49/4, so we can solve by multiplying the nominators and denominators:
49/4 * 2/3 = 49/6;
So she used 49/4 meters of ribbon or 8.167 m.
Now we are going to see how much ribbon is left by subtracting from the total what she used:
12 1/4 - 49/4 = 49/12 meters that she has left.
And out of those she uses 1/2, so we are going to multiply what she has left by 1/2:
49/12 * 1/2 = 49/24 = 2 1/24 = 2.04167 meters that she used of the remaining.
And because she used half she still has the other half of the remaining:
2 1/24 or 2.94167 meters.
Answer:
12 meters
