Two white rabbits produce a brown rabbit. How is this possible? Explain

Physics
1 answer:
kirill115 [55]3 years ago
6 0

Answer:

If one of the parents is white and the other is brown, their offspring will be either white or brown with equal probabilities. Rabbits in this population mate randomly; thus, the probability of mating two white rabbits is the same as the probability of mating between two brown rabbits.

The maximum tension that a 0.80 m string can tolerate is 15 N. A 0.35-kg ball attached to this string is being whirled in a vert
zimovet [89]

Answer:

v=5.86 m/s

Explanation:

Given that,

Length of the string, l = 0.8 m

Maximum tension tolerated by the string, F = 15 N

Mass of the ball, m = 0.35 kg

We need to find the maximum speed the ball can have at the top of the circle. The ball is moving under the action of the centripetal force. The length of the string will be the radius of the circular path. The centripetal force is given by the relation as follows :

F=\dfrac{mv^2}{r}

v is the maximum speed

v=\sqrt{\dfrac{Fr}{m}} \\\\v=\sqrt{\dfrac{15\times 0.8}{0.35}} \\\\v=5.86\ m/s

Hence, the maximum speed of the ball is 5.86 m/s.

If the mass of a wheel is increased by a factor of 7 and the radius is increased by a factor of 15, by what factor is the moment
inn [45]

Answer:

The moment of inertia will be increased by a factor of 1575

Explanation:

Let the moment of inertia of a wheel be given as;

I = \frac{1}{2} mr^2\\\\

where;

I is the moment of inertia of the wheel

m is mass of the wheel

r is radius of the wheel

when the mass is increased by a factor of 7 and the radius is increased by a factor of 15

I_1 = \frac{1}{2}mr^2\\ \\I_2 = \frac{1}{2}(7m)(15r)^2\\\\I_2 =  \frac{1}{2}(7m)(225r^2)\\\\I_2 = 7\times 225[\frac{1}{2}(mr^2)]\\\\I_2 = 1575[\frac{1}{2}(mr^2)]\\\\Recall, \frac{1}{2}(mr^2) = I_1 \\\\I_2 = 1575 I_1

Thus, the moment of inertia will be increased by a factor of 1575

Given: 3x + y = 1.<br><br> Solve for y.<br><br> y = -3 x - 1<br> y = -3 x + 1<br> y = 3 x - 1
maw [93]

Answer:

y = -3x + 1

Explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 3x from both sides of the equation:

3x + y = 1

3x (-3x) + y = 1 (-3x)

y = -3x + 1

y = -3x + 1 is your answer.
