The answer is option D.
Area of sheet, A1 = length × breadth
= (8.5 inch * 2.54 cm) ×11 inch * 2.54 cm)
= 603.22
Now, Mass of sheet, M1 = 4.50 gms
Thus, Area of sheet A2, = 1
And, Mass of sheet, M2 = ?
Thus, Mass of M2 =
= 0.0073
Answer:
112J (3 s.f.)
Explanation:
KE= 1/2mv^2
where KE is kinetic energy, m is the mass in kg, and v is the velocity (or speed to take it simply) in m/s.
KE= 1/2(6)(6.1^2)
KE= 111.63
KE= 112J (3s.f.)
One way is to apply a surface the produces more friction (like sandpaper)
Ella has both dimes (d) and nickels (n) in her piggy bank. She has a total of 36 coins in all, and has 4 more dimes than nickels. Find how much money she has in her piggy bank using a two-variable, two-equation system.

Answer:
Speed changes at the rate of 24 m/s for each second over time.
Explanation:
We are told the object's acceleration is equal to 24 m/s²
Now we know that acceleration can also be defined as the rate of change of speed with time. Also speed has a unit known as m/s.
Thus, we can rephrase the acceleration in this question to mean;
Speed changes at the rate of 24 m/s for every second with time.
