please help me with this questions thank you so much. 1. A wave completes 44.8 cycles in 11.9 seconds. Find its speed if its wavelengh is 7.77 x 10^3 m? 2. And object moving at 1.225m/s accelerates at 6.611m/s2 for 3.330s. Find work and power, if the object's mass is 55.5 kg? 3. A boulder with...

Physics Gr.12: Two resistors of 5 ohms and 9 ohms are connected in parallel. A 4 ohms resistor is then connected in series with the parallel combination. A 6 Volt battery is then connected to the series-parallel combination. What is the current through the 4 ohms resistor?

This is a pretty good question and I have no clue for the answer, can someone help?:confused: According to newtons third law , when a horse pulls on a cart, the cart pulls back with an equal force on the horse. If, in fact, the cart pulls back on the horse as the horse pulls forward on the...

Hello everyone, I am currently taking grade 11 U physics. We are doing a lab (Refraction and Critical Angles) and I have no clue what two questions are asking for!! I just need help understanding the question!!!! Here are the questions: 1) Compare the Ѳc (theta) found experimentally against...

A blimp has an air speed of 10.00m/s. The pilot takes the blimp on a trip 5000m directly into the wind and then 5000m back with the wind. The total time as 20.0 minutes(assume that the turn-around time is negligable). Determine the velocity of the wind relative to the ground. Any help would be...
