How much force would you need to push a 5kg dog on a skateboard to an acceleration of 3m / s2 ?
LekaFEV [45]

Answer:

The force you need to apply would be 15 N.

Explanation:

To find the Force you need to apply, you have to use Newton´s second law     (F = m x a).

F = m x a ⇒ F = 5 kg x 3 m/s²⇒ F = 15 N.

The force would be 15 N.

What current (in a) is required to plate out 1. 22 g of nickel from a solution of ni2 in 0. 50 hour?
Mashcka [7]

The current required to accumulate the 1.22 grams of nickel in 0.5 hours is 2.23 A.

<h3>What is current?</h3>

The current is given as the product of the charge with time. In the electrochemical analysis of the nickel, there will be a reduction of the nickel ion to nickel. The formation is given as:

\rm Ni^{2+}+2e^-\;\rightleftharpoons Ni

There is the deposition of 1 mole of Ni with 2 electrons transfer. The transfer of charge for 1 mole that is 58.7 grams Nickel is:

\rm 58.7\;g=2\;\times\;96487\;C\\58.7\;g=192974\;C

The mass of Ni to be deposited is 1.22 grams. The charge required is given as:

\rm 58.7\;grams\;Ni=192974\;C\\\\1.22\;grams\;Ni=\dfrac{192974}{58.7}\;\times\;1.22\;C\\\\1.22\;grams\;Ni=4010.7\;C

The current required to transfer 4010.7 C of charge in 1800 seconds is given as:

\rm Charge=Current\;\times\;Time\\4010.7\;C=Current\;\times\;1800\;sec\\Current=2.23\;A

Thus, the current required to accumulate the 1.22 grams of nickel in 0.5 hours is 2.23 A.

The longer the bond, the smaller the bond enthalpy. the longer the bond, the smaller the bond enthalpy. false true
Temka [501]

True

As the shorter the bond, the stronger it is hence more energy will be required to overcome this bond

You take an ice cube (mass = 18g) from the freezer (T=-10°C) and place it on the table. Later that day, you notice a puddle of w
murzikaleks [220]
The amount of heat absorbed or released by the system can be determined by the equation:

U = mCpΔT
where:
m = mass of material
Cp = specific heat capacity of material; in this case, Cpwater = 4.186 J/(g-°C)
ΔT = change in temperature of material

U = 18(4.186)(20-(-10)) = 2260.44 Joules or B.
A positive term means energy was absorbed.
