Answer:
3.63m/s²
Explanation:
Given parameters:
Mass of box = 8kg
Net force = 29N
Unknown:
Acceleration of the box = ?
Solution:
To solve this problem, we use Newton's second law of motion which is stated as;
Force = mass x acceleration
Acceleration = =
Acceleration = 3.63m/s²
The final volume of the balloon is 84.75 ml
<u><em>calculation</em></u>
The volume is calculated using Charles law formula
that is V1/T1= V2/T2 where,
V1= 5.00 x10^2 ml
T1= 22.0 °c into kelvin = 22 + 273 = 295 K
V2= ? ml
T2 =0.500 x 10^2 K
make V2 the subject of the formula by multiplying both side by T2
V2 is therefore = T2V1/T1
V2 = (0.500 x 10^2 K x 5.00 x10^2 ml) / 295 K = 84.75 ml
Answer:The ants like daylight and yeah.
Explanation:The ants are probably more active during the day and heat is like adrenaline.
Answer:
Explanation:
β decay is a process in which a nucleus emits an electron.
The nuclear symbol for a β particle is
l
0
-1
e
.
In any nuclear equation, the sum of the subscripts (atomic numbers,
Z
) and the sum of the superscripts (atomic masses,
M
) must be equal on each side of the equation.
For the β decay of iodine 131, we have
131
53
I
→
l
M
Z
X
+
l
0
-1
e
Hence
131
=
M
+
0
, so
M
=
131
53
=
Z - 1
, so
Z
=
53
+
1
=
54
The element
X
with
Z = 54
is
Xe
.
So the equation is
131
53
I
→
131
54
Xe
+
l
0
-1
e
Note that in β decay, the product has the same mass number but an atomic number that has increased by 1.
