Answer:
V= 13 m/s
Explanation:
We're asked to find the magnitude of the object's velocity after a force is applied for
3
s
parallel to its motion.
We'll call the direction it's moving the positive
x
-axis, and the direction of the applied force the positive
y
-axis.
The components of the initial velocity are
v
0
x
=
5
m/s
v
0
y
=
0
(It's moving at
5
meters per second in the straight line we called the
x
-axis.)
We know the object's mass is
3
kg
, and the force applied is
12
N
in the positive
y
-direction. The magnitude of the constant acceleration is thus
a

∑

Since this acceleration is directed upward, and the initial
y
-velocity is
0
, we can use the kinematics equation
v

=
v

y
+
a
y
t
to find the
y
-velocity after
3
seconds.
Plugging in known values, we have

No acceleration was applied in the
x
-direction, so it's
x
-velocity remains
5
m/s
. The magnitude of the velocity is thus
v

The non metals good conductivity any to conduct electric city any time because the metals when we keep into any switch board while we touch we will get shock but non metals not like that
When we discuss radioactive isotope activity, we consider how many decays or disintegrations occur per unit of time. Therefore, activity is determined by the quantity of disintegrations over time. Ah, the becquerel, or B que, is a measurement unit that is widely used to quantify activity. It is equivalent to one decay or one disintegration per second. Therefore, we occasionally shorten it to one d. per s. The curie, denoted by the letters C I, is a second unit we used to denote activity. The result is 1.4 times 10 to the negative 11. Curie's modify this to Beck, Carell's One Curie from curies. His 10 times 10 times 3.7 's Becca Rell And we are aware that one Decorah is equal to one Decay every second. Therefore, we multiply by 1.4 x 10 - 11 times. There are 5 to 5 decays per second, or 3.7 x 10 to the 10 refined. There is one more conversion because my query now asks us what this would be in decays per minute. We multiply 60 by 5.5 to 5 to get the number of decays per minute from our activity and decays per second. This yields 32 decays per minute, which is significant at 30.
<h3>What are isotopes?</h3>
Isotopes are two or more atom types that have the same atomic number (number of protons in their nuclei), location in the periodic table, and chemical element but have distinct nucleon numbers (mass numbers) as a result of having a different number of neutrons in their nuclei. Although the chemical properties of each isotope of a particular element are almost identical, they differ in their atomic weights and physical characteristics.
