Answer:
Acceleration, a = 2.38m/s²
Explanation:
Given the following data;
Mass = 1.01 kg
Force = 2.4N
To find the acceleration;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
- m represents the mass of an object.
- a represents acceleration.
Making acceleration (a) the subject, we have;
Substituting into the equation, we have;
<em>Acceleration, a = 2.38m/s²</em>
<em>Therefore, the magnitude of the acceleration of the ball at the time of the crash is 2.38 meters per seconds square. </em>
Every photon has some energy within it and that energy is called photon energy.
The energy of photon is 
.
Given that, frequency of the photon is 
and Planck's constant is 
.
So the energy of the photon can be calculated by the given formula.
Where 
is plank's constant and 
is the frequency of the photon.
By substituting the values in the above formula, the photon energy is,
The energy of photon is .

Law of conservation of momentum
67*x=4.2*5.6
Answer:
a. 17 μC b. 14.45 J
Explanation:
Here is the complete question
A pair of 10μF capacitors in a high-power laser are charged to 1.7 kV.
a. What charge is stored in each capacitor?
b. How much energy is stored in each capacitor?
a. The charge Q stored in a capacitor is Q = CV where C = capacitance and V = voltage. Here, C = 10μF = 10 × 10⁻⁶ F and V = 1.7 kV = 1.7 × 10³ V.
So, Q = CV = 10 × 10⁻⁶ × 1.7 × 10³ = 1.7 × 10⁻² C = 17 × 10⁻³ C = 17 μC
b. The energy stored in a capacitor is given by W = 1/2CV² = 1/2 × 10 × 10⁻⁶ F × (1.7 × 10³ V)² = 1/2 × 10 × 10⁻⁶ F × 2.89 × 10⁶ V² = 1/2 × 10 × 2.89 × 10⁶ × 10⁻⁶ J = 14.45 J
