1. Pressing force = 10N , Area= 2m2 : Calculate pressure in N/m2 2. Pressing force = 70N, Area = 0.2m2 : Calculate pressure in N/m²
3. Pressing force = 300N , Area = 0.01m?: Calculate pressure N/m
4. Pressing force = 500N, Pressure = 20N/m² : Calculate area in m
5. Area = 0.003m2, Pressure = 15000N/m2 : Calculate the pressing force in N
I am so confused

It's a snowy day and you're pulling a friend along a level road on a sled. you've both been taking physics, so she asks what you think the coefficient of friction between the sled and the snow is. you've been walking at a steady 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
