I think 9 is function

4 0

Answer:

for this test or homework or whatever it is I will give you my opinion of what I know.

7. For number 7 I think it's D but I'm not that sure.

8. when they say all of the following is not a family except will that means that which of the following in the multiple choice is not a type of family, well as so far beginning (C) is not the type of family.

9. this question sees given love and security is an example of...........the family, well to answer is function because love and secure makes up the function of a family without love and secure a family cannot be function that good.

10. I believe the answer is A, but not sure.

11. As we all know, we should wear a rubber boots to prevent electric shock.

In a jump spike, a volleyball player slams the ball from overhead and toward the opposite floor. Controlling the angle of the sp
MAVERICK [17]

Answer:

The ball would have landed 3.31m farther if the downward angle were 6.0° instead.

Explanation:

In order to solve this problem we must first start by doing a drawing that will represent the situation. (See picture attached).

We can see in the picture that the least the angle the farther the ball will go. So we need to find the A and B position to determine how farther the second shot would go. Let's start with point A.

So, first we need to determine the components of the velocity of the ball, like this:

V_{Ax}=V_{A}cos\theta

V_{Ax}=(21m/s)cos(-14^{o})

V_{Ax}=20.38 m/s

V_{Ay}=V_{A}sin\theta

V_{Ay}=(21m/s)sin(-14^{o})

V_{Ay}=-5.08 m/s

we pick the positive one, so it takes 0.317s for the ball to hit on point A.

so now we can find the distance from the net to point A with this time. We can find it like this:

x_{A}=V_{Ax}t

x_{A}=(20.38m/s)(0.317s)

x_{A}=6.46m

Once we found the distance between the net and point A, we can similarly find the distance between the net and point B:

V_{Bx}=20.88 m/s

V_{By}=-2.195 m/s

y_{Bf}=y_{B0}+V_{0}t-\frac{1}{2}at^{2}

0=2.1m+(-2.195m/s)t-\frac{1}{2}(-9.8m/s^{2})t^{2}

-4.9t^{2}-2.195t+2.1=0

t=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}

t=\frac{-(-2.195)\pm\sqrt{(-2.195)^{2}-4(-4.9)(2.1)}}{2(-4.9)}

t= -0.9159s    or   t=0.468s

we pick the positive one, so it takes 0.468s for the ball to hit on point B.

so now we can find the distance from the net to point B with this time. We can find it like this:

x_{B}=V_{Bx}t

x_{B}=(20.88m/s)(0.468s)

x_{B}=9.77m

So once we got the two distances we can now find the difference between them:

x_{B}-x_{A}=9.77m-6.46m=3.31m

so the ball would have landed 3.31m farther if the downward angle were 6.0° instead.

Two conducting spheres with diameters of 0.400 m and 1.00 m are separated by a distance that is large compared with the diameter
PSYCHO15rus [73]

Answer:

Part a)

Q_1 = 2\mu C

Part b)

\Delta V = 4.5 \times 10^4 V

Explanation:

As we know that conducting sphere is treated like spherical capacitor

so we can say

\frac{C_1}{C_2} = \frac{0.4}{1}

also we know that

Q = CV

so charge on two spheres will be in the ratio of their capacitance

Part a)

Q_1 + Q_2 = 7 \mu C

\frac{Q_1}{Q_2}= 0.4

1.4Q_2 = 7\mu C

Q_2 = 5 \mu C

Q_1 = 2\mu C

Part b)

Now potential difference between two sphere can be given as

\Delta V = \frac{Q}{C}

\Delta V = \frac{2\mu C}{4\pi \epsilon_0 R_1}

\Delta V = \frac{2\mu C}{4\pi \epsilon_0(0.400)}

\Delta V = 4.5 \times 10^4 V
