What conditions would you expect to find during an effusive eruption?
Answer:
Effusive eruptions occur when hot, (1200oC) runny basalt magmas reach the surface. Dissolved gases escape easily as the magma erupts, forming lava that flows downhill quite easily. Effusive eruptions build up gently-sloping Shield Volcanoes like Hawaii.

Flag In reaching her destination, a backpacker walks with an average velocity of 1.34 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.68 m/s, due west, urns around, and hikes with an average velocity of 0.447 m/s, due east. (a) How far east did she walk? (b) If she did not turn around and walked due east, how many hours would it take her to reach her destination with an average velocity of 1.34m/s due west?
Answer:
[tex]s_2=-806m[/tex]
Explanation:
From the question we are told that
Velocity 1 [tex]v=1.34m/s \angle west[/tex]
Distance [tex]d=6.44km=>6440m[/tex]
Velocity 2 [tex]v_3=2.68m/s[/tex]
Velocity 3 [tex]v_3=0.447m/s \angle east[/tex]
Generally the equation for VT is mathematically given by
[tex]VT=v_1t_1 +V_2t_2[/tex]
[tex]VT=2.68(2400)-0.447t_2[/tex]
[tex]1.34t_1+1.34t_2=2.68(2400)-0.447t_2[/tex]
[tex]t_2=1804s[/tex]
Therefore
[tex]s_2=v_2t_2=(-0.447)(1804)[/tex]
[tex]s_2=-806m[/tex]

A train moves at 300 km/h. How far will it go in 5 hours?
Answer:
1,500 km
Explanation:
300 km/h
300 kilometers PER HOUR
So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.
300 * 5 = 1,500
The train moves at 1,500 km in 5 hours.

Explanation:
1. Determination of the mass of gasoline
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
The density of a substance is simply defined as the mass of the substance per unit volume of the substance. Mathematically, the density of a substance can be expressed as:
Density = mass / volume
With the above formula, we can obtain the mass of the gasoline as follow:
Density of gasoline = 0.7 Kg/L
Volume of gasoline = 15 L
Mass of gasoline =?
Density = mass / volume
0.7 = Mass of gasoline / 15
Cross multiply
Mass of gasoline = 0.7 × 15
Mass of gasoline = 10.5 Kg
2. Density has various units some are listed below:
I. Kilogram per litre (Kg/L)
II. Kilogram per cubic metre (Kg/m³)
III. Milligram per millilitre (mg/mL)
IV. Gram per millilitre (g/mL)
V. Gram per cubic centimetre (g/cm³)
Considering the options given in the question above, it is evident that second per gram (s/g) is not a unit of density because density is mass per unit volume.

Calculate the running costs of a filament lamp with a 60 W bulb and a CFL lamp with a 15 W bulb for 15 hours.
1 kWh costs 10p.
cost = power (kW) × time (hours) × price (per kWh)
Answer:
the cost of running the bulbs is 11.25p
Explanation:
Given;
cost of running 1 kwh = 10 p
power of filament bulb, P = 60 W
power of the CFL bulb, P = 15 W
time of power consumption, t = 15 hours
Total Energy consumed;
E = (60W + 15W) x 15 hours
E = (75)(15)
E = 1125 Wh
E = 1.125 kWh
Cost of 1.125 kWh = 1.125 x 10p
= 11.25p
Therefore, the cost of running the bulbs is 11.25p

O A. In four piles, organized by suit
B. Stacked in a deck
C. In order of face value
D. Scattered over the ground
SUBMIT
Answer:
D.
Explanation:
Entropy is the measurement of disorder in a system. The greater the entropy the more disorder/mess there is. Options A B and C all have organized systems so D is the only one with the least orderly scenario
Scattered over the ground represents the highest entropy of a deck of playing cards.
What is entropy?Entropy is a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.
Entropy is the measurement of disorder in a system. The greater the entropy the more disorder/mess there is. Options A,B and C all have organized systems so, D is the only one with the least orderly scenario

What is the mass, in grams, of 2.00 moles of H2O?
Answer:
36g
Explanation:
Given parameters:
Number of moles of H₂O = 2moles
Unknown:
Mass of H₂O = ?
Solution:
To solve this problem, use the expression below:
Mass of H₂O = number of moles x molar mass
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of H₂O = 2 x 18 = 36g
