An initially stationary object experiences an acceleration of 6 m/s2 for a time of 15 s. How far will it travel during that time
Tju [1.3M]

Answer:

675m

Explanation:

Given parameters:

Initial velocity  = 0m/s

Acceleration  = 6m/s²

Time  = 15s

Unknown:

Distance traveled by the body = ?

Solution:

To solve this problem; we use the expression;

   S = ut + \frac{1}{2}at²

 Where u is the initial velocity

              t is the time

             a is the temperature

         

Insert the parameters and solve;

  S = 0 x 15 + \frac{1}{2} x 6 x 15²  

  S = 675m

Base your answers to questions 4 and 5 on the informa- tion below

If the sphere is positively charged, the positive rod is repelled by the sphere while the negative rod is attracted by the sphere.

<h3>What is an electrical charge?</h3>

An electrical charge can be positive or negative. From the laws of electrostatics, unlike charges attract while like charges repel. As such the effect observed when the rods are individually brought near the sphere will decide the charge on the sphere.

If the sphere is neutral, there is no effect observed when each rod is brought near the sphere. If the sphere is positively charged, the positive rod is repelled by the sphere while the negative rod is attracted by the sphere.

Gamma rays x rays visible light and radio waves are all types of
bazaltina [42]

Answer:

Electromagnetic waves

Explanation:

Electromagnetic waves are waves that consist of oscillating electric and magnetic fields, that oscillate perpendicularly to each other and perpendicularly to the direction of propagation of the wave (for such a reason, these waves are also called transverse waves).

Electromagnetic waves always travel in a vacuum at the same speed, called speed of light:

c=3.0\cdot 10^8 m/s

and they are classified into 7 different types, according to their frequency. From lowest to highest frequency, we have:

Radio waves

Microwaves

Infrared

Visible light

Ultraviolet

X-rays

Gamma rays

Therefore, gamma rays, x-rays, visible light and radio waves are all types of electromagnetic waves with different frequencies.

I have a problem in this questions?
photoshop1234 [79]

Answer:

8.46E+1

Explanation:

From the question given above, the following data were obtained:

Charge 1 (q₁) = 39 C

Charge 2 (q₂) = –53 C

Force (F) of attraction = 26×10⁸ N

Electrical constant K) = 9×10⁹ Nm²/C²

Distance apart (r) =?

The distance between the two charges can be obtained as follow:

F = Kq₁q₂ / r²

26×10⁸ = 9×10⁹ × 39 × 53 / r²

26×10⁸ = 1.8603×10¹³ / r²

Cross multiply

26×10⁸ × r² = 1.8603×10¹³

Divide both side by 26×10⁸

r² = 1.8603×10¹³ / 26×10⁸

r² = 7155

Take the square root of both side

r = √7155

r = 84.6 m

r = 8.46E+1 m
