The acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².
The given parameters;
- <em>initial velocity of the engine, u = 1341 m/s</em>
- <em>final velocity of the engine, v = 7600 m/s</em>
- <em>time of motion, t = 2 minutes = 2 x 60 s = 120 s</em>
The acceleration of the SRB and main engine is calculated as follows;
Thus, the acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².

Answer:
Charge, 
Explanation:
It is given that,
The number of electron in a RBCs, 
We need to find the total charge of these electrons in the red blood cell. Let it is q. Using the quantization of charge as follows :
q = ne
e is the change on electron
So, the net charge is 
.
Yes, considering lava accommodates rocks that have collapsed of cave walls it is heterogeneous.
Answer:
a)0.364 ns
b)1.43 x 10^-3
c)163.21 x 10^-5 m
Explanation:
mass of the positron is m=9.1 x 10^-31 kg
charge is q=1.6 x 10^-19 C
strength of the magnetic field is B=0.0980 T
kinetic energy is K=2.30 keV=2.30 x 10^3 x 1.6 x 10^-19 J
0.5mv^2=6.68 x 10^-16 J
0.5 x 9.1 x 10^-31 x v^2 =3.68 x 10^-16
v=2.84 x 10^7 m/s
a)the period is T=2πm/qB
=2π(9.1 x 10^-31 )/1.6 x 10^-19x 0.0980
=0.364 ns
b) pitch is p=vcosθ(2πm/qB)
=2.84 x 10^7x cos82(0.364 x 10^-9)
=1.43 x 10^-3
c) radius is r=mvsinθ/qB
=(9.1 x 10^-31 )2.84 x 10^7x sin82/1.6 x 10^-19x 0.098
=163.21 x 10^-5 m
