The motion of a particle

executing S. H. M is given by x

= 0.01 sin 100 ti (t+0.5)

where x is in meter and 't' in

second. The time period is

You cover 10 meters in a time of 1 second. Is your speed the same if you cover 20 meters in 2 seconds?

A certain 100W light bulb has an efficiency of 95%. How much thermal energy will this light bulb add to the inside of a room in 2.5h if the bulb is on for the whole time?

The speed of light in a vacuum is 2.998Ã108 m/s. calculate its speed in miles per hour (miles/h).

My Notes A certain lightbulb has a tungsten filament with a resistance of 21.4 Ω when at 20.0°C and 147 Ω when hot. Assume the resistivity of tungsten varies linearly with temperature even over the large temperature range involved here.

A spider crawling across a table leaps onto a magazine blocking its path. The initial velocity of the spider is 0.870 m/s at an angle of 35.0° above the table, and it lands on the magazine 0.0770s after leaving the table. Ignore air resistance.

A force of 5 N accelerates an object. The object's mass is 50 g. What is the acceleration of the object? (Formula: F=ma)
