Answer:
455165.278 m
Explanation:
P = Power = 3.7 W
v = Velocity = 10.7 m/s
Amount of fat = 4 g
1 gram of fat provides about 9.40 (food) Calories
Energy given by 4 g of fat
Time required to burn the fat
Distance traveled by the bird
The bird will fly 455165.278 m
Which body is in equilibrium?
(1) a satellite orbiting Earth in a circular orbit
. No. The forces on it are unbalanced. There's only one force acting on it ... the force of gravity, pulling it toward the center of the Earth. That's a centripetal force, and the satellite is experiencing centripetal acceleration.
(2) a ball falling freely toward the surface of Earth. No. The forces on it are unbalanced. There's only one force acting on it ... the force of gravity, pulling it toward the center of the Earth. The ball is accelerating toward the ground.
<em>
(3) a car moving with a constant speed along a straight, level road. YES.</em> We don't even need to analyze the forces, just look at the car. It's moving in a straight line, and its speed is not changing. The car's acceleration is zero ! That right there tells us that the NET force ... the sum of all forces acting on the car ... is zero. THAT's called 'equilibrium'.
(4) a projectile at the highest point in its trajectory. No. The forces on it are unbalanced. There's only one force acting on it ... the force of gravity, pulling it toward the center of the Earth. The projectile is accelerating toward the ground.
You can look at magnesium, it can react with oxygen to form oxides. (chemical) it is malleable and a solid at room temperature. (physical)
to measure its density, the mass and volume can be worked out and from this density too. look up the equation, it is quite easy :)
physical changes -- it can be melted, and oxidized <span />
The rotational kinematics allows finding that the response for the time to reach the washing speed is
t = 4.26 s
Kinematics studies the motion of bodies, in the special case that the motion is circular is called rotational kinematics.
θ = w₀ t + ½ α t²
Where θ is the angle, w₀ are the initial angular velocity, α is the angular acceleration and t is the time
Rotational kinematics is written in units of radians, therefore all magnitudes must be reduced,
θ = 6 rev ( ) = 12π rad
In this case the washing machine starts from rest, therefore the initial rotational velocity is zero
θ = ½ α t²
t =
t =
t = 4.26 s
In conclusion using rotational kinematics we can find that the answer for the time to reach the washing speed is
t = 4.26 s
