NEET - CONSERVATION OF MOMENTUM 002 A force of 50 dynes is acted on a body of mass 5gm which is at rest for an interval of 3 sec, then impulse is- (1) 0.16 × 10–3 N-S(2) 0.98 × 10–3 N-S (3) 1.5 × 10–3 N-S (4) 2.5 × 10–3 N-S 2. A body of mass M moving with a speed V collides on a surface at an angle 45 degree without changing its speed the change in momentum of the body will be- (1) MV(ˆj ˆi) (2) MV(ˆi ˆj) (3) 2MV j (4) 2MV j 3. A body of mass 0.5 kg is projected under grav...

NEET - CONSERVATION OF MOMENTUM A space craft of mass M is travelling in space with velocity v. It then breaks up into two parts such that the smaller part m comes to the rest, then the velocity of the remaining part isMv Mv mv Mv (1) M m (2) M m (3) M m (4) m 2. If the KE of a body becomes four times its initial value, then the new momentum will be more than its initial momentum by; (1) 50% (2) 100% (3) 125% (4) 150% 3. A particle of mass 4m which is at rest explodes into three fragme...

NEET - CONSERVATION OF MOMENTUM 003 The centre of mass of a body : (1) Lies always at the geometrical centre (2) Lies always inside the body (3) Lies always outside the body (4) Lies within or outside the body 2. All the particles of a body are situated at a distance R from the origin. The distance of the centre of mass of the body from the origin is (1) = R (2) R(3) > R (4) R 3. Where will be the centre of mass on combining two masses m and M(M > m) : (1) towards m (2) towards M ...

Honors Physics Midterm Questions with Certified Answers What is the difference between speed and velocity? Speed is the measure of how fast an object is moving, while velocity includes both the speed and the direction of the object's motion. How does Newton's Third Law of Motion apply to interactions between two objects? Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction, meaning that when one object exerts a force on a second obj...

RIO SALADO Physics 112 Midterm Questions with Verified Solutions What is the difference between kinetic and potential energy? Kinetic energy is the energy an object has due to its motion, while potential energy is the energy an object has due to its position or configuration. How does the principle of conservation of momentum apply to isolated systems? In an isolated system, the total momentum remains constant if no external forces act on it. What is the role of a force in changin...

Honors Physics - Final Exam Review with Complete Solutions What is the principle of superposition in wave interference? The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves' amplitudes. How does the frequency of a wave relate to its wavelength? The frequency of a wave is inversely related to its wavelength; as the frequency increases, the wavelength decreases, and vice versa. What is the role of an ele...

Which of the following is not considered a pyrimidine? A. C B. T C. U D. G 4. Which of the following is paired correctly? A. A-G B. C-G C. A-U D. G-T 5. Which of the following characterizes a Western blot? A. Antibody/protein hybridization B. DNA/RNA combination C. RNA ...

Honors Physics Final Exam Questions and Answers Graded A+ What is the principle of inertia? The principle of inertia states that an object will not change its state of motion unless acted upon by an external force. How does friction affect the motion of an object? Friction opposes the motion of an object, causing it to slow down or stop. What is the concept of momentum? Momentum is the quantity of motion an object has, which depends on its mass and velocity. What is the dif...
