Question 1 Correct 5.00 points out of 5.00 A 0.200 kg dart is fired horizontally at a speed of 2.75 m / s when it hits a 0.700 kg block ofwood suspended by a string. The nose of the dart sticks into 0.00210 m the wood. Together the dart and block swing upwards from a height of 0.0500 m above a table to 0.128 m above the table. Which of the following is the average force the dart applies to the block during impact? Select one: a. 32.4 N b. 15.1 N c. 1.36 N d. 0.872 N Straighterl...

An object moves along the x-axis. It is moving in the negative x-direction with increasing speed. The xcomponents of its velocity and acceleration are: A) both positive B) velocity negative, acceleration positive C) both negative D) velocity positive, acceleration negative correct answers C) both negative The position of an object in one dimensional motion as a function of time t is given by x(t) = q - bt2 + ct3 where q, b, and c are positive constants. At t = 0, the object's position, veloc...

EVOC Latest 2023 with Verified Solutions what are the 3 newtonian laws 1. every body at rest tends to remains at rest, while every body in motion tends to remain in motion until acted upon by unbalanced external force (also known as inertia or centrifugal force 2. the acceleration of a body is propertional to the force applied and inversely propertional to the mass of the body. (this is teh law of acceleration) the force exerted on an object is equal to its mass times acceleration. 3. for every ...

The tide-generating force is inversely proportional to the cube of the distance. - True There is no horizontal tide-generating force on Earth at points directly below and opposite the Moon. - True The barycenter follows: - a smooth orbit around the Sun. The difference between centripetal forces and gravitational forces is called the: - resultant force. t A If the resultant force has a significant horizontal component (tangential to Earth's surface), it produces tidal bulges on Earth, cre...

Define Wien's Law - The hotter an object, the shorter the wavelength at maximum emission. (The hotter the object the brighter) After a cold front passes what happens to dew point? - it drops, as cold air is typically dry Centripetal force wind - right angles to the wind, in towards the center of curvature ex. hurricanes Convection is the process that? - involves mixing in a fluid Coriolis effect - The effect of Earth's rotation on the direction of winds and currents. Define a category fi...
