It’s both A and B, because technically whenever you drop the ball. It’s called a fumble, and whenever the qb does not catch the snap, the defenders go for it and huddle it so it’s 100% A and B

Thoroughly explain how to balance this chemical equation.
noname [10]
The coefficients are 8 17 1 8

remember that we have to have the same amount of atoms on each side of the equation.
start with C there is 1 on the left and 8 on the right so 8 has to be on the CO. now there is an 8 now on the water there is 1 originally and now we need 8. from water there is now a total of 16 hydrogen plus the 18 from octane for a total of 34. the left has an H2. 34/2 = 17. that is where the 17 comes from

A steel playground slide is 5.25 m long and is raised 2.75 m on one end. A 45.0 kg child slides down from the top starting at re
Temka [501]

Answer:

F=32.24N

Explanation:

From the question we are told that:

Height h= 2.75 m

Lengthl = 5.25 m

Mass m=45kg

Final speed v_f=6.81

Generally the equation for Potential Energy P.E is mathematically given by

P.E=mgh

Therefore

Initial potential energy

P.E_1=45*9.8*2.75 \\\\P.E_1= 1212.75 J

Generally the equation for Kinetic Energy K.E is mathematically given by

K.E=0.5mv^2

Therefore

Final kinetic energy

K.E_2= 1/2*45*6.81*6.81 \\\\K.E_2= 1043.46J

Generally the equation for Work_done is mathematically given by

W=P.E_1-K.E_2\\\\W=169.3

Therefore

F=\frac{W}{d}\\\\F=\frac{169.3}{5.25}

F=32.24N

A truck with 0.410 m radius tires travels at 25.0 m/s. What is the angular velocity of the rotating tires in radians per second?
Eduardwww [97]

relation between linear velocity and angular velocity is given as

v = R\omega

here

v = linear speed

R = radius

\omega = angular speed

now plug in all data in the equation

25.0 = 0.410 \omega

\omega  = \frac{25}{0.410}

\omega = 60.9 rad/s

so rotating speed is 60.9 rad/s
