Different types of fronts produce different patterns of weather. When a cold, dense air mass pushes warmer air, it produces a cold front. A cold front can turn a heat wave into normal summer weather or turn cold winter air into very cold weather. Cold fronts often produce tall cumulonimbus clouds.
Answer:
1.35 m/s in the +x direction
Explanation:
Mass of can of coffee, m = 2.4 kg
Initial velocity of can of coffee, u = 1.5 m/s
Mass of box of macaroni, M = 1.2 kg
Initial velocity of box of macaroni, U = 0 m/s
Final velocity of can of coffee, v = 0.825 m/s
We can find the final velocity of the box of macaroni, V, by using the Principle of Conservation of momentum:
Total initial momentum = Total final momentum
Momentum is given as the product of mass and velocity. Hence:
mu + MU = mv + MV
(2.4 * 1.5) + (1.2 * 0) = (2.4 * 0.825) + (1.2 * V)
3.6 + 0 = 1.98 + 1.2V
1.2V = 3.6 - 1.98 = 1.62
=> V = 1.62/1.2
V = 1.35 m/s
The final velocity of the box of macaroni is 1.35 m/s and it is in the +x direction.
The answer would be:
A, a space station orbiting Earth.
Answer:
the coin does not slide off
Explanation:
mass (m) = 5 g = 0.005 kg
distance (r) = 15 cm = 0.15 m
static coefficient of friction (μs) = 0.8
kinetic coefficient of friction (μk) = 0.5
speed (f) = 60 rpm
acceleration due to gravity (g) = 9.8 m/s^{2}
lets first find the angular speed of the table
ω = 2πf
ω = 2 x π x 60 x 
ω = 6.3 s^{-1]
Now lets find the maximum static force between the coin and the table so we can get the maximum velocity the coin can handle without sliding
static force (Fs) = ma
static force (Fs) = μs x Fn = μs x m x g
Fs = 0.8 x 0.005 x 9.8 = 0.0392 N
Fs = ma
0.0392 = 0.005 x a
a = 7.84 m/s^{2}
= a x r
= 7.84 x 0.15
Vmax = 1.08 m/s
ωmax = 
ωmax = 
= 7.2 s^{-1}
now that we have the maximum angular acceleration of the table, we can calculate its maximum speed in rpm
Fmax = 
Fmax = 
= 68.7 rpm
since the table is rotating at a speed less than the maximum speed that the static friction can hold coin on the table with, the coin would not slide off.
The theory drives this teacher's practices is Behaviorist.
<h3>
Who is a Behaviorist?</h3>
- A methodical approach to analyzing human and animal behavior is called behaviorism.
- It is predicated on the idea that behavior is either a reflex brought on by the combination of specific antecedent stimuli in the environment or a result of the individual's history, particularly reinforcement and punishment contingencies, in conjunction with their current state of motivation and controlling stimuli.
- Although most behaviorists acknowledge the significance of inheritance in affecting behavior, they place a greater emphasis on environmental factors.
- As a response to depth psychology and other traditional forms of psychology, which frequently struggled to make predictions that could be tested experimentally but were derived from earlier research in the late nineteenth century, such as when Edward Thorndike invented the law of effect, behaviorism emerged in the early 1900s.

Question:
In a science class, the teacher sets the room up with a variety of objects such as tubs of water, aluminum foil, and clay. The question on the board is: What makes objects float? Students enter the class and, in small groups, explore the materials. make decisions regarding what data to collect. and discuss the data's meaning. Students are urged to think, ask questions, and draw conclusions on their own. What theory drives this teacher's practices? Select one
A. Behaviorist/Behavioral
B. Humanistic
C. Cognitive
D. Nativist/Innatist
