X = 1/2
Maybe you haven't finished typing the first two answer choices but x = 1/2 should be one of them.
Here's step by step work:
<span>–3x + 1 + 10x = x + 4
7x + 1 = x + 4
6x = 3
x = 3/6
x = 1/2</span>
Answer:
33300J
Explanation:
Given parameters:
Mass of ice = 100g = 0.1kg
Initial Temperature of water = 0°C
Final temperature = 0°C
Unknown:
Amount of energy = ?
Solution:
The amount of energy is given by;
Amount of energy = mL
m is the mass
L is the latent heat of fusion = 3.33 x 10⁵ J/kg
Amount of energy = 0.1kg x 3.33 x 10⁵J/kg
Amount of energy = 33300J
Answer:
The term Geo means earth. In short it is a study of earth in a much wider perspective.
1.The subject is very important as it helps up to learn about people living in various continents or countries (lifestyle,occupation,culture and society).
2.It also helps us to learn about the various climatic conditions at various places of earth,topography,flora and fauna(plants and animals).
Geography is defined as 'the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources and political and economic activities.'
Answer:
d. planes of weak bonding between certain layers of atoms
Explanation:
Cleavage , is a type of planar feature of the rock , which develops due to the metamorphism and deformation .
It is a secondary type of rock foliation , i.e. , the separation between two rocks .
They are formed in fine grained rocks which is made from minerals , under high pressure .
The weak bonding between layers of atom , generates a cleavage .
A dirt road would heat up and cool down the quickest
Explanation:
This is because the soil gets heated up faster than water which is a slow conductor of heat so water gets heated gradually.
On the other hand, the soil gets cooled down quickly than water which gets cooled down slowly. Soil absorbs heat whereas water reflects heat so when cooling down water loses a lot of energy.
