How could you keep an objects acceleration the same if the force acting on the object were double?

Physics

Bogdan [553]4 years ago

You can keep an object's acceleration constant if the force acting on it is double by adding another force going in the opposite direction of the first force. The second force will have to be as strong as the first force was originally in order for the acceleration to be the same. This is the same concept as if you have 2 of something, double it to get 4, and subtract 2 again. You'll end up with the same value you started with.

Measuring the size of a specific object might include which of these SI units?
defon

D. Meter, Kilogram

Explanation:

  • There are certain units for the measurements things which are around us.
  • This is the SI units for the measurement of the size of the objects.
  • SI units are international unit systems, they are one who accepted around the world.
  • It is called the International System of Units, used to expresses the phenomenon happens around us in a scientific method
  • Here, the meter is the unit for Length in the International System of Units and Kilogram is to represent the mass of the object in SI units system.

An electron is released from rest in a unifor electric field and accelerates to the north at a rate of 145 m/s^2. What is the ma
julsineya [31]

Answer:

E = 8.26*10⁻¹⁰ N/C, due south.

Explanation:

  • Assuming no other forces acting on the electron than the electrostatic force due to the electric field, we can apply Newton's 2nd law as follows:

       F = -eE =ma (1)

  • Solving for E, we can find its magnitude as follows:

       E =\frac{m*a}{e} = \frac{9.1e-31 kg*145m/s2}{1.6e-19C} = 8.26e-10 N/C (1)

  • The direction of the electric field is by definition the one that would take a positive test charge, so if the electron is accelerated to the north, the electric field would exactly oppose to this direction, so it is directed due south.

Which type of foot PPE must you wear if electrical shock is ever a possibility with your job?
ira [324]
The appropriate PPE(personal protective equipment) to be worn for foot protection against electric shock is boots retrofitted with rubber soles. Rubber does not conduct electricity and so will safeguard against electric shocks.

Other personal protective equipment used in a lab or industry can include safety glasses, rubber gloves, protective clothing and masks and respirators. PPE goes hand in hand with personal behaviour, personal grooming and housekeeping.

An electron is pushed into an electric field where it acquires a 1-V electrical potential. Suppose instead that two electrons ar
sleet_krkn [62]

Answer:

0.5 V

Explanation:

The electric potential distance between different locations in an electric field area is unaffected by the charge that is transferred between them. It is solely dependent on the distance. Thus, for two electrons pushed together at the same distance into the same field, the electric potential will remain at 1 V. However, the electric potential of one of the two electrons will be half the value of the electric potential for the two electrons.
