Answer:
1.02s
Explanation:
In this situation the following equation will be useful:

Where:
 is Marissa's car final velocity
 is Marissa's car initial velocity
 is Marissa's car constant acceleration (assuming this is the acceleration, since 1269 m/s^{2} does not make sense)
 is the time it takes to accelerato from  to 
Answer:
Available usage time for the computer = 10.185 hrs
Explanation:
for the dryer;
I = 15 A, V=240 V , t= 55min,
convert time from min to sec. t = 55*60 =3300 sec
Energy = IVt
Energy = 15*240*3300
Energy = 11,880,000 J
=11,800 KJ
using the energy for the clothes dryer to calculate for the time spent on the computer,
Energy = IVt
for the computer;
I = 2.7A V=120V , t=?


t=36,666.7sec
convert this value to hour by dividing by 3600

Answer:
The Alkali Metals
sodium is a member of the alkali metal family with potassium (K) and lithium (Li). Sodium's big claim to fame is that it's one of two elements in your table salt. When bonded to chlorine (Cl), the two elements make sodium chloride (NaCl).
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
