Answer:
7. 01 * 10^7 N/C
Explanation:
Parameters given:
Distance, y = 2.9 m
Radius, R = 2.9 cm = 0.029m
Charge, Q = 5.0 µC = 5 * 10^(-6) C
Given that:
E = 2πKσ(1- [y/(R² + y²)]) j^
Charge density, σ, is given as:
σ = Q/A = Q/πR²
=> E = 2πKQ/πR² (1- [y/(R² + y²)]) j^
E = 2KQ/R² (1 - [y/(R² + y²)]) j^
E = (2 * 9 * 10^9 * 5 * 10^(-6) / 0.029²) (1 - [2.9/(0.029² + 2.9²)]) j^
E = 107015.46 * 10^3 *(1 - 2.9/8.41) j^
E = 107015.46 * 10^3 * 0.655 j^
E = 7.01 * 10^7 j^ N/C
The magnitude of the electric field is 7.01 * 10^7 N/C. The j^ shows the direction.
Answer: Calendar
Explanation: I'm pretty sure it is calendar.
Answer:
The correct answers are -
1. b. pump the brake pedal rapidly
2. d. all of the above
3. c. your power brakes and power steering won't work very well
4. a. gasoline
5. b. power-assist failure
Explanation:
Brakes help in stopping the vehicle by causing resistance to wheels. IF brake failure it is advised to pump the breaks rapidly in order to cause resistance. Engine failure can be caused by various reasons such as a broken timing gear, no fuel, or getting extremely heated.
In the case of stalling of engine most common effects as power steering not working properly or power brakes not working well. The flooded engine means the engine has too much gasoline that it wont starts.

Answer:
The magnitude of the acceleration of the 19 kg block is 1.414 m/s²
Explanation:
From Newton's second law of motion;

where;
m is the mass of the objects involved, kg
a is the acceleration of the object, m/s²
different forces on the block and string
⇒force due to 15 kg block
=mgcosθ = 15×9.8×cos20 = 15×9.8×0.9396
= 138.12 N
⇒Tensional Force on 19 kg mass:
T = mg = 19×9.8 = 186.2 N

186.2 - 138.12 = a(15+19)
48.08 = a(34)
a = 48.08/34
a = 1.414 m/s²
Therefore, the magnitude of the acceleration of the 19 kg block is 1.414 m/s²
