Shari uses the data in the table to predict how her weight on Venus would compare with her weight on Earth.

spin [16.1K]

Answer : <em>Her weight is lower on Venus because the acceleration due to gravity is lower.</em>

Explanation :

Venus is also called as Earth's twin. This is because both the mass and the size of Earth and Venus are almost same. The acceleration due to gravity on earth is $9.8\ m/s^2$ while on Venus is $8.87\ m/s^2$ .

So, when Shari measure her weight on Venus she found her weight is lower on Venus. This is because the acceleration due to gravity is lower on the surface of Venus as compared to the Earth.

Since, $w=mg$

i.e. weight depends on g.

<em>So, correct prediction is (b)</em>

A canoe floats in a lake. Inside the canoe is a 25 kg steel solid ball. If the ball is thrown into the lake, does the level of t

Rus_ich [418]

Answer:

Explanation:

volume of ball bearing = 4/3 π r³

= 4/3 x 3.14 x 1.5³

= 14.13 cc.

if D be the density of steel , weight of the ball bearing

= 14.13 x D x g

For the first case , water will be displaced to keep it floating

weight of displaced water will be equal to weight of steel

weight of displaced water = 14.13 Dg

mass of displaced water = 14.13 D

volume of displaced water = mass / density of water

= 14.13 D / d ; (where d is density of water) .

Now when the steel ball bearing is dipped in water , it will displace water equal to its volume only and it will be drowned

its volume = 14 .13 cc

14.13 D / d > 14.13 ( because D/d is more than one , since D > d )

volume of water displaced in first case is greater

water level will go up higher in first case .

Hence in the second case water level will go down .

Same will happen in case of 25 kg steel .

On April 15, 1999, a South Korean cargo plane crashed due to a confusion over units. The plane was to fly from Shanghai, China,

sattari [20]

Answer:

993 m or 3257 ft

Explanation:

The captain was told to fly at at 1500 ft altitude. At the rate of 3.28 ft to 1 m, this is

$\dfrac{1500}{3.28}=457$ metres.

Since he was at 1450 m, he thought he was above the correct altitude by

1450 - 457 = 993 m.

In feet, this is

993 * 3.28 = 3257 ft

Where would you most likely find regional metamorphism? associated with a mountain belt associated with a volcano associated wit

vladimir1956 [14]

Regional metamorphism is a type of metamorphism in which the minerals and the textures of the rocks are changed or altered due to the effect of pressure and heat over a wide area or region.
This type of metamorphism often results in metamorphic rocks that are strongly foliated.
Metamorphism usually occurs in the folds of thrust mountain belts.

Answer: You would most likely find regional metamorphism associated with a mountain belt.
