They will attract each other. If they were of the same charge they would repel each other.

Answer: The two balls will attract each other.

Explanation:

As we know, like charges repel each other and unlike charges attract each other.

We are given in the question, that two plastic balls are there having opposite charges that are hung by a string and are close to each other. These two charges have different charges and hence, they are considered as unlike charges.

So, these two balls will attract each other.

|| Suppose a plane accelerates from rest for 30 s, achieving a takeoff speed of 80 m/s after traveling a distance of 1200 m down

rjkz [21]

Answer:

600 m is required for smaller plane to reach its takeoff speed.

Explanation:

We have equation of motion

80 = 0 + a x 30

a = 2.67 m/s²

Now finding distance traveled by second flight

v² = u²+2as

40² = 0²+2 x 2.67 x s

s = 300 m

So 300 m is required for smaller plane to reach its takeoff speed.

how do i.... Find the angle between each pair of vectors below. (1 point each) a. a = 2x + 3y a = 4x + 2y

Shalnov [3]

Recall that the dot product between two vectors $\mathbf a$ and $\mathbf b$ satisfies

$\mathbf a\cdot\mathbf b=\|\mathbf a\|\|\mathbf b\|\cos\theta$

where $\|\mathbf x\|$ denotes the norm of a vector $\mathbf x$ , and $\theta$ is the angle between the two vectors.

So if $\mathbf a=(2,3)$ and $\mathbf b=(4,2)$ , then

$(2,3)\cdot(4,2)=\|(2,3)\|\|(4,2)\|\cos\theta$

$\implies2\cdot4+3\cdot2=\sqrt{2^2+3^2}\sqrt{4^2+2^2}\cos\theta$

$\implies\cos\theta=\dfrac{14}{\sqrt{13}\sqrt{20}}$

$\implies\theta\approx29.7^\circ$

How much energy can be stored in a spring with k = 470 n/m if the maximum possible stretch is 17.0 cm ?

MrRissso [65]

The strain energy stored in a linear spring is
SE = (1/2)*k*x²
where
k = the spring constant
x = the extension (or compression) of the spring

Given:
k = 470 N/m
x = 17.0 cm = 0.17 m

Therefore
SE = 0.5*(470 N/m)*(0.17 m)² = 6.7915 J

Answer: 6.8 J (nearest tenth)
