I went for a walk the other day. I went four blocks east, then seven blocks south, then one block west and finally

nalin [4]

Answer:

a) distance is 4+7+1+8=20 blocks

b) displacement is 10 blocks

Explanation:

find displacement: x and y

x axis displacement = 4-1 = 3 blocks

y axis displacement = -7+8= 1 block

displacement = the square root of 3^2 + 1^2

= 9+1 = 10 blocks.

You can find the angle of displacement with respect to the initial position using trig identities, if you wish.

Of the following, ________ should have the highest critical temperature. Of the following, ________ should have the highest crit

3241004551 [841]

Answer:

Explanation:

Critical temperature is the temperature above which gas cannot be liquefied, regardless of the pressure applied.

Critical temperature directly depends on the force of attraction between atoms, it means stronger the force of higher will be the critical temperature. So, from the given options H2 should have the highest critical temperature because of high attractive forces due to H bonding.

Hence, the correct option is H2.

how many calories is in one peanut if the volume of water is 10 mL and the water temperature is rise 4 degrees celsius

liraira [26]

Answer:

40.02 calories

Explanation:

V = 10 mL = 10g

we know t went <em>up</em> by 4°C, this is our ∆t as it is a change.

Formula that ties it together: Q = mc∆t

where,

Q = energy absorbed by water

m = mass of water

c = specific heat of water (constant)

∆t = temperature change

Q = (10 g) x (4.186 J/g•°C) x (4°C)

Q = 167.44 J

Joules to Calories:

167.44 J x 1 cal/4.184 J = 40.02 calories

(makes sense as in image it is close to the value).

Density is an intensive physical property that relates the mass of an object to its volume. Density, which is simply the mass of

xz_007 [3.2K]

Answer: 40731.8 grams of this gasoline would fill a 14.6gal tank

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Given : Mass of gasoline = ?

Density of the gasoline = $0.737g/ml$

Volume of the gasoline = 14.6gal = 55267.01 ml (1gal=3785.41ml)

Putting in the values we get:

$0.737g/ml=\frac{mass}{55267.01ml}$

${\text {mass of gasoline}}=40731.8g$

Thus 40731.8 grams of this gasoline would fill a 14.6gal tank
