the rocket has a mass m and a velocity v relative to Earth, and hence a ... thrust is greater in outer space than in the atmosphere or on the launch pad.
Answer:
a= - 1.2 m/s²
Direction of a : in the negative x- direction
Explanation:
Because the ball moves with uniformly accelerated movement we apply the following formula:
vf²=v₀²+2*a*d Formula (1)
Where:
d:displacement in meters (m)
v₀: initial velocity in m/s
vf: final velocity in m/s
a: acceleration in m/s²
Known data
v₀ = 9.0 m/s
vf= 3.00 m/s
d = 30.0 m.
Problem development
We replace data in the formula (1) to calculate acceleration :
vf²=v₀²+2*a*d
(3)²= (9)² + (2* 30)*a
9=81+(60)*a
9-81=(60)*a
-72= (60)*a
a= -72/60
a= - 1.2 m/s²
Direction of a : in the negative x- direction
Answer:
option C.
Explanation:
The correct answer is option C.
The owner is at the top of the organizational pyramid he owns the organization and all the investment is done by the owner.
Strategic teams do all the strategy related work like how to increase production, decrease the losses, how to increase the quality, etc.
Operational team deals with the work which is related to taking work, assigning work and giving the result to the higher authority.
hence, the work of Andy Benton matches with the duties of the Operation team
Answer:
Any medium solid, liquid or gas is required for sound waves to travel.
Explanation:
A sound wave requires a medium to travel. Sound waves are mechanical waves that is why these waves require a medium to travel. Sound waves can travel through solids, liquids, and gases.
In solids, the particles of the medium are closely packed together as compared to liquids and gases. In liquids, particles are less tightly packed and almost negligible in gases.
Therefore sound waves produce vibration in the dense or solid medium. Denser the medium faster the sound waves travel. However sound waves can not travel through empty space.
Answer:
<h3>The answer is 16.67 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>16.67 m/s²</h3>
Hope this helps you
