Plz help i really dont understand 1. A popular sprinter of mass 60 kg, was running a 100 m race. Her velocity was measured over a 10.0 s period. The results are recorded in Table 1.
Velocity, v/ms^-1 0.0 2.5 5.0 7.5 10.0 10.0
Time, t/s 0.0 2.0 4.0 6.0 8.0 10.0

a. Use the results from Table 1 to plot a graph of Velocity versus Time
b. Determine the slope of the graph over the first 6.0 s of the race.
c. What quantity does the slope of the graph represent?

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2
