Answer:
17 m/s south
Explanation:
= Mass of dog = 10 kg
= Mass of skateboard = 2 kg
v = Combined velocity = 2 m/s
= Velocity of dog = 1 m/s
= Velocity of skateboard
In this system the linear momentum is conserved
The velocity of the skateboard will be 17 m/s south as the north is taken as positive
Answer:
the vertical distance between the two object will increase uniformly when they are dropped after a fixed interval of time
Explanation:
Since airplane is moving horizontally with constant speed v
so when object is dropped from the plane then the speed of the object will be same as that of the speed of the airplane
so we can say that two object when dropped after some interval of time then they always lie in same vertical line
now we know that they both have same acceleration in vertical line so the motion of two objects relative to each other in vertical direction is always uniform motion because they have no acceleration with respect to each other
So the vertical distance between the two object will increase uniformly when they are dropped after a fixed interval of time
Answer:
26.56°
Explanation:
μ= 0.5
F = ?
N =?
Fs = μN
Fs = force acting due to friction (on an inclined plane)
N = normal force.
μ= coefficient of friction
μ= tanΘ
μ= tan 0.5
Θ = tan⁻¹ 0.5
Θ = 26.56°
The angle in which is required for the box to start moving across the inclined plane is 26.56°
<span>Poet Kuangchi Chang did not remain in China long enough to be "re-educated." Following the Communist takeover he fled to the United States. His poem "Garden of My Childhood" describes China before the revolution as a peaceful, idyllic garden with a violent horde rapidly approaching. A vine, the wind, and the sea are each personified, and each beckons for him to run. It is not until "eons later," when he is "worlds away," that his "running is all done," and he finds himself at his destination: another garden, just like the one he had left behind.</span>
Answer:
Competitive forces model
Explanation:
A Competitive forces model is the important tool which is used in the strategic analysis to determine the competitiveness in an organization. The model is commonly known as the "Five Force Model of Porter", which includes five forces — intensity of a rivalry, the bargaining ability of the buyers, threat of the potential new entrants, the bargaining power of a supplier, and the threat of substitute goods or services.
It affects the organizations's ability to compete as well as the strategy to succeed.
