An object with no net force cannot experience acceleration as per Newton's Second Law. However, it is moving, so it is experiencing velocity. Since there is no acceleration, we can say that the object experiences constant velocity.
Answer:
3.55 T
Explanation:
Applying,
F = BILsin∅.............. Equation 1
Where F = Force, B = magnetic Field, I = current, L = Length of the wire, ∅ = Angle between the wire and the magnetic field
make B the subject of the equation
B = F/ILsin∅.................. Equation 2
From the question,
Given: F = 2.45 N, L = 3.00 cm = 0.03 m, I = 23.0 A, ∅ = 90° (Perpendicular)
Substitute these values into equation 2
B = 2.45/(0.03×23×sin90)
B = 2.45/0.69
B = 3.55 T
The density of the metal is important because if its more dense than water it will sink but if its lighter than water it will float
Momentum = (mass) x (speed)
3300 kg-m/s = (61 kg) x (speed)
Speed = (3300 kg-m/s) / (61 kg)
Speed = 54.1 m/s (about 121 mph)
Answer:
x = vt
Explanation:
At constant speed, distance = speed × time.
x = vt
To solve for time:
t = x / v
This equation works because at constant speed, there is no acceleration.
Δx = v₀ t + ½ at²
Δx = v₀ t + ½ (0) t²
Δx = v₀ t
