Answer:
2.42 N
Explanation:
The total force is the upward 7.28 N force minus the weight.
7.28 N − (0.495 kg) (9.81 m/s²)
7.28 N − 4.86 N
2.42 N
Yes, it does. Acceleration is defined as the rate of change of velocity. Velocity is the rate of change of position with a given direction i.e. speed with direction.So even though the speed of the turning car is constant the velocity is not. This means that the velocity is changing, and the rate of change of velocity is called acceleration. Hence, the car is accelerating.
Answer:
it is good so far
i just passed my math test
Explanation:
Answer:
the apparent weight of the astronaut in the rocket is 3723 N.
Given:
acceleration = 34 
mass of astronaut = 85 kg
To find:
Apparent weight of the astronaut = ?
Solution:
Total weight of the astronaut in a rocket is given by,
W = w + F
W = apparent weight of the astronaut
w = weight of astronaut on earth surface = mg
F = force acting on the astronaut = ma
W = mg+ma
W = m (g+a)
W = 85 (9.8 + 34)
W = 3723 N
Thus, the apparent weight of the astronaut in the rocket is 3723 N.
An electric toaster takes in electrical energy from the power outlet and converts it into heat<span>, very efficiently. If you want your toast to cook quickly, you need a toaster that radiates as much </span>heat<span> as possible each second onto your bread.</span>
