I think the answer is Cirrus. They are flat feathery clouds that usually stretch long distances over the sky.
<span>The physical feel of H2O is the same regardless of the sample size of the substance. Water feels wet whether it is a single drop or equivalent in volume to an ocean. It is the way the substance feels no matter how much or how little there is present.</span>
Answer:
94.29619%
Explanation:
= Mass of bullet= 0.012 kg
= Mass of block = 0.2 kg
= Initial Velocity of bullet= 550 m/s
= Initial Velocity of block = 0 m/s
= Final Velocity of bullet = 20 m/s
= Final Velocity of block
As the linear momentum of the system is conserved
Change in kinetic energy is given by
Percentage change is given by
The percent of the initial kinetic energy of the bullet block system is lost during the collision is 94.29619%
Answer:
The truck must travel by 95.16 km/h to stay beneath the airplane
Explanation:
Lets explain how to solve the problem
How fast must a truck travel to stay beneath an airplane that is moving
105 km/h at an angle of 25° to the ground
The truck moves a long the horizontal ground
The airplane moves 105 km/h at an angle 25° to the ground
The truck must moves with velocity equal the horizontal component
of the velocity of the airplane to stay beneath the airplane
The angle between the line represented the velocity of the airplane
and the ground is 25°
→ The horizontal component of the velocity = v cos(25)
→ The velocity of the airplane is 105 km/h
→ The horizontal component = 105 cos(25) = 95.16 km/h
The velocity of the truck = the horizontal component of the airplane
<em>The truck must travel by 95.16 km/h to stay beneath the airplane</em>
An educated guess pretty much
