What is most likely the relationship between Mendel’s rules of genetics and Darwin’s idea of biological evolution?
xenn [34]

Answer:

Darwin's theory of natural selection lacked an adequate account of ... Darwinian principles now play a greater role in biology than ever before, .... Sadly, even if Mendel had lived to see the rediscovery of his work, he probably .... evolutionary forces are acting, a genetic equivalent to Galileo's law of inertia.

Flashlight has resistance of 2.4 what voltage is applied by the batteries if the current is 2.5a
Sergeeva-Olga [200]

Answer:

6 voltage is applied by the batteries.

Explanation:

To solve this sort of problem involving current, resistance and voltage, we use the relation:<em> </em><em>Voltage</em><em>= </em><em>Current x Resistance</em>.

From the problem, the following have been given:

Resistance= 2.4 ohms.

Current= 2.5 amps.

Required: Voltage?

Fix the values of current and resistance into the relation:

Voltage= <em>2.5 x 2.4</em>

            =6 volts.

A rigid tank contains air at a pressure of 70 psia and a temperature of 55 ˚F. By how much will the pressure increase as the tem
Katyanochek1 [597]

Answer:

P_2 = 62.69 psi

Explanation:

given,

P₁ = 70 psia               T₁ = 55° F    = (55 + 459.67) R

P₂ = ?                         T₂ = 115° F    = (115 + 459.67) R

we know,

p = ρ RT

ρ is the density which is constant

R is also constant

now,

\dfrac{P_2}{P_1} =\dfrac{T_2}{T_1}

\dfrac{P_2}{70} =\dfrac{55+459.67}{115+459.67}

    P_2 = 62.69 psi

Hence, the increase in Pressure is equal to P_2 = 62.69 psi

Which of the following will cause an induced current in a coil of wire? Which of the following will cause an induced current in
svp [43]

Answer:

a magnet being moved into or out of the coil

Explanation:

Electromagnetic induction on a coil of wire depends on relative motion between the wire and a magnetic field. If there is no relative motion between the magnet and the coil, no current is included on the wire. This implies that a stationary magnet around a coil of wire will not produce induced current on a stationary conductor or wire.

Summarily, whenever a conductor is placed in a changing magnetic field, current is induced on the conductor.
