Maps and Globes share the following features:
Both are scale Models.
Explanation:
A globe is a scale model of the Earth that presents the most accurate depiction of geographic information such as area, distance, and direction.
A map is a two dimensional representation or a drawing of the earth’s surface, or a part of it, on a flat surface, according to a scale. Thus it is also a scale model.
A globe differs from a map. It is a three dimensional sphere representing the whole Earth.
A map is usually used to represent a specific part of the Earth and is used for Navigation. It has details and symbols. However, a globe can not be used for such details.
A globe can be used to get a broad-level picture of the world.

Answer:
rightwards is the positive velocity
Rightwards is the positive elicitation:
I think it is the core and outer core.
hope this helped.
Answer:
a positive test charge will move in the field
Explanation:
The direction of an electric field corresponds to the direction of motion of a positive test charge in the electric field. In fact:
- the electric field produced by a positive charge points outwards the charge --> this is because when a positive test charge is placed in this field, it will feel a repulsive force (because two positive charges repel each other), so it will move away from the positive charge that produces the field
- the electric field produced by a negative charge points towards the charge itself--> this is because when a positive test charge is placed in this field, it will feel an attractive force (because a positive and a negative charge attract each other), so it will move toward the negative charge that produces the field.
Answer:
The value of mass 1, m1= 6/5m
The value of mass 2, m2= 3/5m
Explanation:
case 1:
here tension and the acceleration will be:
for m1;
- mg-T=ma
- 2mg - 2T = 2ma .....1.
for m2:
adding the both equations,
2mg - 2T + 2T-mg = 2ma + ma/2
a = 2/5 g
putting the value of a into the equation 1.
mg - T = m* (2/5)g
T = 3/5 ( mg )
now
case 2:
The two identical blocks are released from the rest, the tension remains the same as the case 1.
so,
for m1:
for m2:
adding both equations we get,
2T-m2g + 2m2g - 2T = 0
m2 = m1 / 2
T = m1*g / 2
here we know that
T (case1) = T (case2)
3/5 ( mg ) = m1*g / 2
m1 = 6/5 m
hence
m2 = 3/5 m
