Answer:
is that a question or a statement lol
Explanation:
Answer:
20 rad/s^{2}
Explanation:
weight / force (F) = 150 N
radius (r) = 0.5 m
mass (m) = 15 kg
angular acceleration = tangential acceleration / radius
where
- tangential acceleration = force/ mass = 150/15 = 10 m/s^{2}
- substituting the above into the equation for angular acceleration we have
angular acceleration = 10 / 0.5 =
Answer:
<u>Speed = 1.2 m/s</u>
Explanation:
<em>Convert 20 min into seconds</em>
<em>1min= 60sec</em>
20min = 20*60 sec
<em>20 min= 1200sec</em>
Time = 1200 sec
Distance = 1000m
Speed =
Speed =
<u>Speed = 1.2 m/s</u>
<u></u>
<em>Hope this helps.</em>
Answer:
The answer is a. Jumper
Explanation:
The change in the momentum is represented by the equation
Acceleration of any body is calculated by the product of the mass of the body and with the velocity the same mass is moving.
Since it is mentioned in the statement that m is the mass of the jumper then velocity will also be of the jumper to calculate the change in the momentum.
If the mass of bugle cord is taken, then its velocity will be taken for the equation.
Answer:
Force is repulsive hence direction of force is away from wire
Explanation:
The first thing will be to draw a figure showing the condition,
Lets takeI attractive force as +ve and repulsive force as - ve and thereafter calculating net force on outer left wire due to other wires, net force comes out to be - ve which tells us that force is repulsive, hence direction of force is away from wire as shown in figure in the attachment.
