Answer:
10v / 7
Explanation:
Using the conservation law of momentum
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
m v - 0.7 m v₁ = ( 0.7 m + m) 0 m/s since the cart stuck together after collision. taken right to be positive and left to be negative
m v - 0.7 m v₁ = 0
- 0.7 m v₁ = -m v
v₁ = -m v / - 0.7 m = 10v / 7
Gravity is affected by the size of an object and the distance between the objects. When the mass of an object increases the force of gravity increases as well.
Explanation:
Electrostatic induction, also known as "electrostatic influence" or simply "influence" in Europe and Latin America, is a redistribution of electric charge in an object, caused by the influence of nearby charges.[1] In the presence of a charged body, an insulated conductor develops a positive charge on one end and a negative charge on the other end.[1] Induction was discovered by British scientist John Canton in 1753 and Swedish professor Johan Carl Wilcke in 1762.[2] Electrostatic generators, such as the Wimshurst machine, the Van de Graaff generator and the electrophorus, use this principle. Due to induction, the electrostatic potential (voltage) is constant at any point throughout a conductor.[3] Electrostatic Induction is also responsible for the attraction of light nonconductive objects, such as balloons, paper or styrofoam scraps, to static electric charges. Electrostatic induction laws apply in dynamic situations as far as the quasistatic approximation is valid. Electrostatic induction should not be confused with Electromagnetic induction
Answer:
A = 26.875 rad/s²
Explanation:
<u>Given the following data;</u>
Initial angular speed, Uw = 150 rads/s.
Final angular speed, Vw = 580 rads/s.
Time = 16 seconds.
To calculate the angular acceleration;
From kinematics equation;
At = Vw - Uw
Where;
- A is the angular acceleration.
- t is the time
- Vw is the final angular speed.
- Uw is the initial angular speed.
Substituting into the formula, we have;
A*16 = 580 - 150
16A = 430
A = 430/16
<em>A = 26.875 rad/s²</em>
