Answer:
K_A = 32.2 10⁶ J
Explanation:
In this exercise we must relate the quantities given to find the kinetic energy
Asteroid A data
m_A = 3.5 m_B
v_A = 2.0 v
they also give the value of the kinetic energy of asteroid A
K_B = 2.3 10⁶ J
the expression for scientific energy is
K = ½ m v²
let's replace
K_A = ½ m_a V_a2
K_A = ½ 3.5 m_B (2.0 v_B)^2
K_A = 3.5 2² (½ m_B v_B²)
K_A = 14 K_B
K_A = 32.2 10⁶ J

Answer:
The energy stored in the solenoid is 0.18J
Explanation:
We need to obtain the inductance in order to calculate the energy:
The energy stored in the solenoid is given by:
The sentence is accurate, therefore TRUE is the answer.
Answer:
Explanation:
Given that,
Initial velocity, u = 10 m/s
Final velocity, v = 0 (stops)
Time, t = 30 s
We need to find the acceleration of the lion.
We know that,
Acceleration = rate of change of velocity
So, the acceleration of the lion is 
.
