Answer:
Condensation
Explanation:

Answer:
Based on color theory it would come out as brown
Explination:
Basic color theory states the primary colors are red yellow and blue. Expanding that to the rainbow you know. Red plus yellow equals orange. Yellow plus blue equals green. And blue plus red equals purple. Red and Green are opposite colors and when you combine opposite colors you get brown
Answer:
18km/h
Explanation:
w - water
s - Swimmer
E- Earth
V (w,E) = 8 km/h
V (s,w) = 10 km/h
V (s,E) = ?
V ( s,E) = V (s,w) + V (w,E)
= 10 + 8
= 18 km/h
Answer:
.
Explanation:
The box is sliding with a constant speed in a fixed direction (to the right.) In other words the velocity of this box is constant. Hence, this box would be in a translational equilibrium. The acceleration of this box would be zero.
By Newton's Second Law of motion, the net force on this box would be . In other words, forces on this box are balanced.
The question is asking for the size of the friction on the box. Assuming that the floor is horizontal. The friction on this box would also be horizontal,
The only other force that could balance that friction would be the push to the right. The direction of this push is horizontal (to the right.) Hence, the entirety of that would be in the horizontal direction.
Thus, forces on this box in the horizontal direction would be:
- The push to the right.
- Friction that opposes the rightward motion of the box (that is, to the left.)
Since these two forces must balance each other, the size of the friction would also be .
Given: Please see the attached image below.
To be able to
subtract vectors, we can either use the parallelogram method or the triangle
method. Take note that the only difference is that alternatively adding vectors
A and B, we will instead be adding A and – B. When we ponder of vector subtraction, we must
anticipate about it in terms of adding a negative vector. A negative vector has the same magnitude as the
original vector, however, it has an opposite direction.
So in this problem, the two vectors that will have the
largest magnitude are A & F when subtracted (i.e., when one vector is
subtracted from the other).
