Q. Racing drivers like to warm up the tyres of their car as soon as possible. One reason is that warm tyres grip the road better but the temperature also affects the pressure of the air into he tyres.
a. elucidate what happens to the movement of the molecules as the air in the tyres warms up.
b. describe what happens to the pressure of the air in the tyres as it warms up.
A proton is placed in an electric field of intensity 700 N/C. What is magnitude and direction (towards or away from the field) of the acceleration of this proton because of this field? The charge on a proton is +1.6 x 10-19 C and the mass of a prot..
A car of mass = 1200 traveling at 65 enters a banked turn covered with ice. The road is banked at an angle , and there is no friction between the road and the car's tires. What is the radius of the turn if = 20 (assuming the car continues in unifo..
A daredevil on the motorcycle leaves the end of a ramp with a speed of 36.0 m/s. If his speed is 34.20 m/s while he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance. In meters
The coefficient of kinetic friction is 0.50. A horizontal force of magnitude 87 N begins to pull directly on the block. In unit-vector notation, what are the resulting accelerations of (a) block and (b) slab.
A car starts from rest and travels for 10s with a uniform acceleration of +2.4 m/s2. The driver then applies the brakes, causing a uniform negative acceleration of -2.0 m/s2.
Unpolarized light with an intensity of 275 W/m2 passes by the two polarizers whose transmission axes are at an angle of 30.0° with respect to each other. What is an intensity of the light transmitted through both polarizers.
An asteroid is discovered heading straight toward Earth at 13km/s. An international team manages to attach a giant rocket engine to the asteroid. The rocket fires for 10 mins, after which the asteroid is moving at 28 degrees to its original path at a..
Using the data calculate the average speed of blood flow in the major arteries of the body which have a total cross-sectional area of about 2.0 cm2.
A total electric charge of 4.50 nC is distributed uniformly over the surface of a metal sphere with a radius of 22 cm. The potential is zero at a point at infinity. Find the value of the potential at 45 cm from the center of the sphere.
A wooden raft has a mass of 76 kg. When empty it floats in water (density 1000 kg/m3) with 51 percent of its volume submerged. What mass of sand can be put on the raft without it sinking.
A scuba diver at a depth of 42.0 m below the surface of the sea off shores of Panama City, where the temperature is 7 °C, releases an air bubble with volume 18 cm3.
Two carts with masses of 5.00 kg and 2.64 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.46 m/s correspondingly. The carts stick together after colliding head-on. Find the final speed.
