Answer:Thermal is to heat as <u><em>absorb</em></u> is to water.

Explanation:

Water is able to absorb heat - without increasing much in temperature - better than many substances. This is because for water to increase in temperature, water molecules must be made to move faster within the water; this requires breaking hydrogen bonds, and the breaking of hydrogen bonds absorbs heat.

The answer is Absorb I’m pretty sure.

A(n) ___ object is not electrically neutral.

Korvikt [17]

Answer:

No, there are always protons, neutrons, and electrons. When an object is neutral, it means the positive and negative charges sum to zero (are equal and opposite). NO, if an object has no net charge it simply means that the amount of positive and negative charges (protons and neutrons) are the same.

When two point charges are a distance dd part, the electric force that each one feels from the other has magnitude F.F . In orde

Harman [31]

Answer:

In order to make this force twice as strong, F' = 2 F, the distance would have to be changed to half i.e. r' = r/2.

Explanation :

The electric force between two point charges is directly proportional to the product of charges and inversely proportional to the square of the distance between charges. It is given by :

$F=\dfrac{kq_1q_2}{r^2}$

r is the separation between charges

$F\propto \dfrac{1}{r^2}$

$r=\sqrt{\dfrac{1}{F}}$

If F'= 2F

$r'=\dfrac{1}{\sqrt{2F} }$

In order to make this force twice as strong, F' = 2 F, the distance would have to be changed to half i.e. $r'=\dfrac{1}{\sqrt{2F} }$ . Hence, this is the required solution.

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 .

Answer: velocity = 79.6m/s, distance covered = 139.6m and velocity when distance is 10.0m = 61.611m/s

Explanation:

First step is to take a direction of motion, so to avoid issues with negative sign, I take my direction of motion as the positive y axis which makes the parameters positive.

The object is of a free fall thus it has a constant acceleration of g = 9.8m/s².

a) initial velocity (u) = 60m/s, g = 9.8m/s², time taken (t) =2s, we need to get velocity at that time using the formulae below

v = u + at

v = 60 + (9.8)* 2

v = 60 + 19.6

v = 79.6m/s

b) to get the distance traveled at t =2s, we use the formulae below

s =ut + 1/2at² where s = distance covered.

s = 60 * 2 + 1/2 * 9.8 * 2²

s = 120 + 1/2 *9.8 * 4

s = 120 + 9.8 * 2

s = 120 + 19.6

s = 139.6m

c) to get the velocity (v) when distance traveled (s) = 10m, we use the formulae below.

v² = u² + 2as

v² = 60² + 2( 9.8)(10)

v² = 3600 + 196

v² = 3796

v = √3796

v = 61.611m
