Please share assumptions and work I'm not sure where I keep going wrong **Problem Statement:**A self-supported steel plate with a thickness of 8 cm and an initial temperature of 20°C passes through a convective oven at a temperature of 1980°C. What is the core temperature of the plate after 2 minutes?**Given Data:**- Convective heat transfer coefficient, \( h = 500 \text{ W/m}^2\text{K} \)- Thermal conductivity of steel, \( k_{\text{steel}} = 63.9 \text{ W/mK} \)- Specific heat of steel, \( C_{\text{steel}} = 434 \text{ J/kgK} \)- Density of steel, \( \rho_{\text{steel}} = 7832 \text{ kg/m}^3 \)- Thermal diffusivity of steel, \( \alpha_{\text{steel}} = 18.8 \times 10^{-6} \text{ m}^2/\text{s} \)**Assumptions and Notes:**- Neglect radiation.- State all assumptions and show all work. **Instructions:**In solving this problem, ensure to apply principles of heat transfer, particularly considering the conduction within the plate and convection from the surface to the surrounding environment. Utilize the appropriate heat transfer equations, possibly involving transient heat conduction analysis.

A penguin starts from rest and accelerates across the snow at a constant rate until he hits the ice, as depicted in the figure below. He then throws himself down and begins to slide along on the frictionless ice. He then goes over the edge into an ice gully and slides up a vertical ice cliff on the other side. Speeds up to here then starts sliding Highest point. that he reaches Starts at rest D Snow Ice F a) Draw a curved line on your paper that represents the shape of the snow and ice (you don't have to draw the penguins). Add points to your drawing that are like the labeled points above. Along your line, draw an arrow to represent the penguin's veloc- ity at each of the labeled points, including roughly scaling the lengths of the velocity vectors to represent the penguin's speed at each point. If it is zero at any point then write "v = 0" by the point. b) Draw arrows to represent the direction of the penguin's acceleration at each of the labeled points. If the acceleration is zero at…
Projectile motion A projectile is launched from the origin, which is a point 50 ft from a 30-ft vertical cliff (see figure). It is launched at a speed of 50√2 ft/s at an angle of 45° to the horizontal. Assume the ground is horizontal on top of the cliff and that only the gravitational force affects the motion of the object.a. Give the coordinates of the landing spot of the projectile on the top of the cliff.b. What is the maximum height reached by the projectile?c. What is the time of flight?d. Write the integral that gives the length of the trajectory.e. Approximate the length of the trajectory.f. What is the range of launch angles needed to clear the edge of the cliff?
