For y= 2x squared + x - 1 the x-intercepts and the turning point respectively are?

physics
The two angled ropes used to support the crate in Figure P5.7 can withstand a maximum tension of 1500 N before they break. What is the largest mass the ropes can support?

Chemistry
In a titration of 35.00 mL of 0.737 M S, __________ mL of a 0.827 M KOH solution is required for neutralization.

chemistry
how would you, explain ans how calcium chloride [CaCl2] is bonded.

physics
Initial velocity, (u), is given, so is acceleration, (g), so is the distance (s), 28.4m. Use v^2=u^2+2as and solve for v.

earth science
descibe the advanages of plotting data in graph form

Physics
Eric, I'm not sure what you need, but if it's Physics tuition (or Math)try Khan Academy. Hundreds of short vids. Hope Jiskha don't mind this post.

Physics
Force = Massx acceleration. Find the accel using v=u+at, solving for a. v is the final velocity (0); u is the initial (9.4), t is time (0.2) Then x by 110 kg. to get the force in Newtons.
