Answer:

Assuming a constant force, if the mass of object increases, the acceleration will decrease and if mass of a object decreases, the acceleration will increase. Also if the force applied to object increases the acceleration will also increase whereas if the force applied decreases, the acceleration will also decrease.

Explanation:

We know that according to newton's second law of motion,

F = ma, where F is force applied, m is mass of an object and a is measure of body accelerated with the applies force.

a = F/m

Assuming force is constant, we get

a α 1/m, that is acceleration is inversely proportional to mass. Hence if mass of an object decreases the acceleration of object will increases and vice versa.

Also from equation, F = ma, we infer that F α a . That is the force applied is directly proportional to amount the body is accelerated. . Hence if force applied increases then the acceleration will also increase and vice versa

A step up transformer has 250 turns on its primary and 500 turns on it secondary. When the primary is connected to a 200 V and t

Zina [86]

Answer:

2000 W

Explanation:

First of all, we need to find the output voltage in the transformer, by using the transformer equation:

$\frac{V_1}{N_1}=\frac{V_2}{N_2}$

where here we have

V1 = 200 V is the voltage in the primary coil

V2 is the voltage in the secondary coil

N1 = 250 is the number of turns in the primary coil

N2 = 500 is the number of turns in the secondary coil

Solving for V2,

$V_2 = N_2 \frac{V_1}{N_1}=(500) \frac{200 V}{250}=400 V$

Now we can find the power output, which is given by

P = VI

where

V = 400 V is the output voltage

I = 5 A is the output current

Substituting,

P = (400 V)(5 A) = 2,000 W

Suppose we have three hypothetical atomic nuclei: A, B, and C. Nucleus A has 7 protons and 7 neutrons. Nucleus B has 5 protons a

alina1380 [7]

Answer:

Nucleus A with 7 protons and 7 neutrons and Nucleus C with 7 protons and 5 neutrons are isotopes of the same elements

Explanation:

Isotopes are elements that have the same atomic structure but different molecular structure. An atom that has the same atomic number but different mass number are known to be isotopes.

The proton of an atom is the same as its atomic number while the sum of the proton and neutron is equal to its mass number.

According to the question, nuclei that has the same number of proton are isotopes of the same element. Therefore nuclei A and C with 7 protons each are isotopes of the same element since they have the same atomic number i.e number of proton = atomic number.

Their atomic masses of nuclei A and C are 14 and 12 respectively
