What is it called when an atom can pass electrons?

Physics
1 answer:
fiasKO [112]3 years ago
7 0

Answer:

Ionic bonding.

Explanation:

According to our crude, conceptual definition, chemical bonds can form either by electron transfer between atoms or by sharing of electrons. ... When atoms lose or gain electrons, they become what are called ions. Loss of electrons leaves an atom with a net positive charge, and the atom is called a cation.

You are riding a bicycle. You apply a forward force of 150 N, and you and the bicycle have a combined mass of 90 kg. What is the
Ymorist [56]

<u>Answer</u>

1.667 m/s²

Using the Newton's second law of motion;

force is directly proportional to the rate of change of momentum and it takes place in the direction of force.

i.e F = change in momentum

F = (mv - mu)/t

   =m(v-u)/t

   = ma

∴ F =ma

  a = F/m

      = 150/90

      = 1.667 m/s²

A water heater warms 35 l of water from a temperature of 22.7 c to a temperature of 83.7
fgiga [73]
The amount of energy needed to increase the temperature of a substance by \Delta T is given by
Q=m C_s \Delta T
where
m is the mass of the substance
C_s is its specific heat capacity
\Delta T is the increase in temperature

The water volume is V=35 L= 35 dm^3 = 0.035 m^3, since its density is d=1000 kg/m^3, the mass of this sample of water is
m=dV=(1000 kg/m^3)(0.035 m^3)=35 kg

The water specific heat capacity is C_s = 4.18 kJ/kg ^{\circ}C

and the increase in temperature is \Delta T=83.7 ^{\circ}C-22.7 ^{\circ}C=61^{\circ}C

Therefore, the amount of energy needed is
Q=mC_s \Delta T=(35 kg)(4.18 kJ/kg ^{\circ}C)(61^{\circ}C)=8924 kJ = 8.92 \cdot 10^6 J

A radiographer stands six feet from the x-ray source when performing a portable chest exam and receives an exposure of 2 mGy. If
telo118 [61]

Answer:

  I₂ = 8 mG

Explanation:

The intensity of a beam is

          I = P / A

Where P is the emitted power which is 3) 3

           

Let's use index 1 for the initial position of r₁ = 6 ft and 2 for the second position r₂ = 3 ft

          I₁ A₁  = I₂  A₂

           I₂ = I₁ A₁ / A₂

The area of ​​the beam if we assume that it is distributed either in the form of a sphere is

           A₁ = 4π r²

We substitute

            I₂ = I₁ (r₁ / r₂)²

           I₂ = 2 (6/3)²

           I₂ = 2 4

           I₂ = 8 mG
