To save fuel, some truck drivers try to maintain a constant speed when possible. A truck traveling at 110.0 km/hr approaches a car stopped at the red light. When the truck is 211.7 meters from the car the light turns green and the car immediately begins t...

You are at standing at a window in the University tower that is 42.0 meter above the ground. Your physics professor (who is 2.12 m tall) is walking on the ground below, approaching to tower at a speed of 1.12 m/s. You are holding an egg, which you would l...

A cannon ball is fired from ground level with a speed of 86.0 m/s at an angle of 32 deg. above the horizontal. A 8.5 m tall wall is located 265 m away from the cannon. By how much does the cannon ball clear the wall? In the previous problem, what is the s...

Consider the initial value problem y'' +5y'+6y=0, y(0)=4.87 and y'(0)=Beta where Beta>0 Determine the coordinates t_m and y_m of the maximum point of the solution as functions of Beta.

A block of weight 4.8 N is at rest on a horizontal table. An upward vertical force of 0.6 N is applied to the block by means of a string. What is the magnitude of the force exerted by the block on the table top?

Three forces, F1 = 9.2 N, F2 = 7.8 N and F3 = 8.3 N are acting on a small box of mass 47.0 kg. If the box is moving in the direction of F2 at constant speed, what is the magnitude of the combination of F2 and F3

A bronze cannon ball with a mass of 4.5 kg is fired vertically from a small cannon and reaches a height of 10.0 m. If the canon is now aimed at an angle 33 degrees above the horizontal, calculate the horizontal distance the cannon ball would travel before...

A stone is dropped from the top of a 83.0 m tall building. How far above the ground is the stone 1.60 seconds before it reaches the ground?

A 115.0 kg box is pushed by a horizontal force F at constant speed up a frictionless ramp which makes an angle of 46.0 deg with the horizontal. Find the magnitude of the applied force F. what is the magnitude of the normal force between the ramp and the b...

A box of mass 5.0 kg starting from rest slides down a 1.8 m long ramp inclined at an angle of 22.0 deg. from the horizontal. If the ramp is frictionless, how long will it take the box, starting from rest, to reach the bottom of the ramp? if the frictionle...

Hi! I am taking the Unit 8 Lesson 10 chem test now and I have a C in this class so I need to get all the answers correct... If you don't know all that's ok but if you know some please help, thank you! (Connections Academy) 1. In a nuclear reaction, which...

I don't Understand your answer

1b

I haven't done mine yet, since yours hasn't been graded yet when it is can you please tell me... It would be greatly appreciated... I just really need to pass this 😅

Actually I took the test and you are correct! Tysm 💙💙 1. the total number of protons 2. the number of protons in the atom changes 3. the spontaneous emission of radiation 4. mashing two marshmallows together 5. There must be a way for unstable nuclei to...

My teachers are busy with state testing happening, so I haven't gotten my feedback on those essays sorry...

Ok, I got my feedback back For 16 I put: Because the alpha particle was emitted than the equation/reaction is balanced. I know this because the nuclear reaction requires a breakdown of any element and also the release of particles that are radioactive. In...
