Ask Your Teacher A trough is 16 ft long and its ends have the shape of isosceles triangles that are 2 ft across at the top and h

zloy xaker [14]

Answer:0.210 ft/min

Explanation:

Given

Length of trough $L=16 ft$

width of base $b=2 ft$

height of triangle $h=1 ft$

From Similar triangles property

$\frac{4}{2x}=\frac{1}{y}$

$2y=x$

volume of water in time t

$V=\frac{1}{2}\times (2x\cdot y)\cdot$

$V=16xy$

$V=32y^2$

differentiating

$\frac{\mathrm{d} V}{\mathrm{d} t}=32\times 2\times y\times \frac{\mathrm{d} y}{\mathrm{d} t}$

at $y=8 in.\approx 0.667 ft$

$9=64\times 0.667\times \frac{\mathrm{d} y}{\mathrm{d} t}$

$\frac{\mathrm{d} y}{\mathrm{d} t}=\frac{9}{64\times 0.667}$

$\frac{\mathrm{d} y}{\mathrm{d} t}=0.210 ft/min$

Matter's resistance to a change in motion is called _____ and is directly proportional to the mass of an object. For an object t

sergeinik [125]

The correct answer is B (Inertia)

We define inertia as the resistance to change of the state of motion. That is, a body tends to remain in its state of motion or rests unless an external for acts on it. The quantity depends on the mass of the body. If the body is heavy, it requires a large force to overcome the inertia.

Q4. What is the speed of light in a block of glass that<br> has an Index of refraction of 1.11?

mrs_skeptik [129]

Refractive index(n)= speed of light in vacuum/ speed of light in medium.
Since refractive index is 1.11, and usually we know that the speed of light is 300,000km/s, simply divide 300,000km/s over 1.11. That is, 270,270.2703 when simply rounding, its 270,270 km/s.

BRAINLIEST WILL BE MARKED FOR THE FIRST ANSWER

Andreyy89

Answer:

98.4 N

Explanation:

Given that the body weighs 800 N on earth.

Thus,

Weight = mass x acceleration due gravity

i.e W = mg

800 = m x 10

m = $\frac{800}{10}$

= 80 kg

The mass of the body is 80 kg.

To be able to determine its weight on the planet, we have to first calculate the gravitational pull of the planet.

But,

g = $\frac{GM}{r^{2} }$

Where: G is the Newton's universal gravitation, M is the mass of the planet and r is the radius of the planet.

g = $\frac{6.674*10^{-11} *2.986*10^{24} }{(12.742*10^{6})^{2} }$

= $\frac{1.9929*10^{14} }{1.6236*10^{14} }$

= 1.2275

g = 1.23 m/ $s^{2}$

Thus,

Weight of the body on the planet = mg

= 80 x 1.23

= 98.4 N

The weight of the body on the planet is 98.4 N

When a ball is tossed in the air and reaches the top of its arc, which of the following quantities are zero? Choose one or more:

Lady_Fox [76]

Answer:

option 'b' and 'c'

Explanation:

when we throw ball in upward direction.

acceleration on the body will never be zero because there will always be acceleration due to gravity i.e. 'g' will be acting on it.

and force of 'mg' will also be acting on the body, where m is the mass of the body.

so,

at the top the parameters which will be zero will be velocity and speed.

at the top most point the ball will change it's direction for that velocity will have to be zero at that point.
