S1 s2 are finite sets If s1 equals n s2 equals m then prove that s1us2 equals n plus m?
It cannot be proven because it is not true. Suppose S1 = {0,1,2,3} and S2 = {0,5,10} then S1 u S2 = {0,1,2,3,5,10} then |S1| = n = 4, |S2| = m = 3 but |S1 u S2| = 6 which is NOT n+m = 7
What is 98 divided by 50?

What is 490 divided by 5?
98
What is the quotient when 4876 is divided by 98?

9.8 m divided by s2?
4.9
If the speed of an object changes from 121 m/s to 98 m/s during a time interval of 12 s, what is the acceleration of the object?
B -1.92 m/s2
What is the potential energy of 5.0kg object located 2.0 m above the ground?
PE = m•g•h, where m is mass in kg, g is 9.8m/s2, and h is height in meters.PE = 5.0kg x 9.8m/s2 x 2.0m = 98kg•m2/s2 = 98 Joules
What does the s stand for in m divided by s2?
The "s" in m/s^2 stands for seconds, representing the unit of time in the expression for acceleration.
How do you work out the acceleration?
F=m x a a=F/m (m/s2) a=(vend-vbeginning)/(tend-tbeginning) m/s2
If the speed of an object changes from 121 ms to 98 ms during a time interval of 12 s what is the acceleration of the object?
-1.92 m/s2
Is accleration equal to velocity divided by time?
Yes acceleration equals velocity divided by time i.e a=v/t and it's S.I unit is m/s2
What is the mass of an object which accelerates at 0.4 m divided s2 with a net force of 12 N?
F = ma =>m = F/a = 12/0.4 = 30 grams
S1 s2 are finite sets If s1 equals n s2 equals m then prove that s1us2 equals n plus m?
It cannot be proven because it is not true. Suppose S1 = {0,1,2,3} and S2 = {0,5,10} then S1 u S2 = {0,1,2,3,5,10} then |S1| = n = 4, |S2| = m = 3 but |S1 u S2| = 6 which is NOT n+m = 7
What are the units for the slope of a velocity-time graph?
Force, in Newtons, can be expressed as Kg*m/s2. Acceleration can be expressed as m/s2. If you divide it out, you get:= N / (m/s2)
What is the gravity pull on your moon?
The acceleration of gravity on the surface of the moon is 1.623 m/s2 . (9.807 m/s2 on Earth)
What will be mass of a body having acceleration 2.5 meter per second square by an ionic force?
F = m Am = F / 2.5The mass will be the (ionic force) divided by 2.5 m/s2 .
